Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552664, here are decompositions:

43 + 31552621 = 31552664
61 + 31552603 = 31552664
127 + 31552537 = 31552664
271 + 31552393 = 31552664
277 + 31552387 = 31552664
313 + 31552351 = 31552664
457 + 31552207 = 31552664
607 + 31552057 = 31552664

Showing the first eight; more decompositions exist.
