Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542162, here are decompositions:
- 13 + 542149 = 542162
- 31 + 542131 = 542162
- 43 + 542119 = 542162
- 79 + 542083 = 542162
- 109 + 542053 = 542162
- 139 + 542023 = 542162
- 163 + 541999 = 542162
- 211 + 541951 = 542162
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 542,162 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 542162 first appears in π at position 751,625 of the decimal expansion (the 751,625ordinal-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.
