Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552616, here are decompositions:

13 + 31552603 = 31552616
37 + 31552579 = 31552616
79 + 31552537 = 31552616
127 + 31552489 = 31552616
223 + 31552393 = 31552616
229 + 31552387 = 31552616
307 + 31552309 = 31552616
313 + 31552303 = 31552616

Showing the first eight; more decompositions exist.
