Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146240, here are decompositions:
- 19 + 146221 = 146240
- 37 + 146203 = 146240
- 43 + 146197 = 146240
- 67 + 146173 = 146240
- 79 + 146161 = 146240
- 163 + 146077 = 146240
- 181 + 146059 = 146240
- 229 + 146011 = 146240
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 146,240 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 146240 first appears in π at position 163,984 of the decimal expansion (the 163,984ordinal-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.
