Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146430, here are decompositions:
- 7 + 146423 = 146430
- 13 + 146417 = 146430
- 23 + 146407 = 146430
- 41 + 146389 = 146430
- 47 + 146383 = 146430
- 61 + 146369 = 146430
- 71 + 146359 = 146430
- 83 + 146347 = 146430
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 146,430 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 146430 first appears in π at position 301,990 of the decimal expansion (the 301,990ordinal-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.
