Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146428, here are decompositions:
- 5 + 146423 = 146428
- 11 + 146417 = 146428
- 47 + 146381 = 146428
- 59 + 146369 = 146428
- 131 + 146297 = 146428
- 137 + 146291 = 146428
- 179 + 146249 = 146428
- 311 + 146117 = 146428
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 146,428 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 146428 first appears in π at position 924,306 of the decimal expansion (the 924,306ordinal-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.
