Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146042, here are decompositions:
- 19 + 146023 = 146042
- 31 + 146011 = 146042
- 73 + 145969 = 146042
- 79 + 145963 = 146042
- 109 + 145933 = 146042
- 139 + 145903 = 146042
- 163 + 145879 = 146042
- 181 + 145861 = 146042
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 146,042 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 146042 first appears in π at position 769,967 of the decimal expansion (the 769,967ordinal-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.
