Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146388, here are decompositions:
- 5 + 146383 = 146388
- 7 + 146381 = 146388
- 19 + 146369 = 146388
- 29 + 146359 = 146388
- 41 + 146347 = 146388
- 71 + 146317 = 146388
- 79 + 146309 = 146388
- 89 + 146299 = 146388
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 146,388 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 146388 first appears in π at position 569,655 of the decimal expansion (the 569,655ordinal-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.
