Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 25604, here are decompositions:
- 3 + 25601 = 25604
- 43 + 25561 = 25604
- 67 + 25537 = 25604
- 151 + 25453 = 25604
- 157 + 25447 = 25604
- 181 + 25423 = 25604
- 193 + 25411 = 25604
- 283 + 25321 = 25604
Showing the first eight; more decompositions exist.

The digit sequence 25604 first appears in π at position 421,420 of the decimal expansion (the 421,420ordinal-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.
