Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604254, here are decompositions:

197 + 31604057 = 31604254
263 + 31603991 = 31604254
503 + 31603751 = 31604254
641 + 31603613 = 31604254
677 + 31603577 = 31604254
701 + 31603553 = 31604254
743 + 31603511 = 31604254
827 + 31603427 = 31604254

Showing the first eight; more decompositions exist.
