Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18674, here are decompositions:
- 3 + 18671 = 18674
- 13 + 18661 = 18674
- 37 + 18637 = 18674
- 151 + 18523 = 18674
- 157 + 18517 = 18674
- 181 + 18493 = 18674
- 193 + 18481 = 18674
- 223 + 18451 = 18674
Showing the first eight; more decompositions exist.

The digit sequence 18674 first appears in π at position 209,763 of the decimal expansion (the 209,763ordinal-suffix:rd 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.
