Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542718, here are decompositions:
- 5 + 542713 = 542718
- 31 + 542687 = 542718
- 131 + 542587 = 542718
- 139 + 542579 = 542718
- 151 + 542567 = 542718
- 167 + 542551 = 542718
- 179 + 542539 = 542718
- 181 + 542537 = 542718
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 542,718 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 542718 first appears in π at position 245,307 of the decimal expansion (the 245,307ordinal-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.
