Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604552, here are decompositions:

19 + 31604533 = 31604552
43 + 31604509 = 31604552
181 + 31604371 = 31604552
193 + 31604359 = 31604552
211 + 31604341 = 31604552
241 + 31604311 = 31604552
271 + 31604281 = 31604552
619 + 31603933 = 31604552

Showing the first eight; more decompositions exist.
