Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542564, here are decompositions:
- 7 + 542557 = 542564
- 13 + 542551 = 542564
- 31 + 542533 = 542564
- 67 + 542497 = 542564
- 97 + 542467 = 542564
- 103 + 542461 = 542564
- 163 + 542401 = 542564
- 193 + 542371 = 542564
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 542,564 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 542564 first appears in π at position 639,234 of the decimal expansion (the 639,234ordinal-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.
