Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552564, here are decompositions:

11 + 31552553 = 31552564
293 + 31552271 = 31552564
311 + 31552253 = 31552564
353 + 31552211 = 31552564
587 + 31551977 = 31552564
761 + 31551803 = 31552564
881 + 31551683 = 31552564
971 + 31551593 = 31552564

Showing the first eight; more decompositions exist.
