Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604626, here are decompositions:

17 + 31604609 = 31604626
23 + 31604603 = 31604626
173 + 31604453 = 31604626
239 + 31604387 = 31604626
269 + 31604357 = 31604626
569 + 31604057 = 31604626
593 + 31604033 = 31604626
797 + 31603829 = 31604626

Showing the first eight; more decompositions exist.
