Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542464, here are decompositions:
- 3 + 542461 = 542464
- 17 + 542447 = 542464
- 23 + 542441 = 542464
- 227 + 542237 = 542464
- 257 + 542207 = 542464
- 281 + 542183 = 542464
- 311 + 542153 = 542464
- 347 + 542117 = 542464
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 542,464 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 542464 first appears in π at position 641,746 of the decimal expansion (the 641,746ordinal-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.
