Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604594, here are decompositions:

37 + 31604557 = 31604594
61 + 31604533 = 31604594
97 + 31604497 = 31604594
211 + 31604383 = 31604594
223 + 31604371 = 31604594
283 + 31604311 = 31604594
313 + 31604281 = 31604594
331 + 31604263 = 31604594

Showing the first eight; more decompositions exist.
