Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604370, here are decompositions:

11 + 31604359 = 31604370
13 + 31604357 = 31604370
23 + 31604347 = 31604370
29 + 31604341 = 31604370
59 + 31604311 = 31604370
67 + 31604303 = 31604370
71 + 31604299 = 31604370
73 + 31604297 = 31604370

Showing the first eight; more decompositions exist.
