Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542412, here are decompositions:
- 11 + 542401 = 542412
- 41 + 542371 = 542412
- 89 + 542323 = 542412
- 113 + 542299 = 542412
- 131 + 542281 = 542412
- 149 + 542263 = 542412
- 151 + 542261 = 542412
- 193 + 542219 = 542412
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 542,412 and was likely granted around 1895.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 542412 first appears in π at position 304,558 of the decimal expansion (the 304,558ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
