Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604722, here are decompositions:

3 + 31604719 = 31604722
41 + 31604681 = 31604722
113 + 31604609 = 31604722
269 + 31604453 = 31604722
419 + 31604303 = 31604722
503 + 31604219 = 31604722
593 + 31604129 = 31604722
971 + 31603751 = 31604722

Showing the first eight; more decompositions exist.
