Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604330, here are decompositions:

19 + 31604311 = 31604330
31 + 31604299 = 31604330
67 + 31604263 = 31604330
103 + 31604227 = 31604330
139 + 31604191 = 31604330
193 + 31604137 = 31604330
397 + 31603933 = 31604330
487 + 31603843 = 31604330

Showing the first eight; more decompositions exist.
