Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542736, here are decompositions:
- 13 + 542723 = 542736
- 17 + 542719 = 542736
- 23 + 542713 = 542736
- 43 + 542693 = 542736
- 53 + 542683 = 542736
- 137 + 542599 = 542736
- 149 + 542587 = 542736
- 157 + 542579 = 542736
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 542,736 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 542736 first appears in π at position 413,732 of the decimal expansion (the 413,732ordinal-suffix:nd 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.
