Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552474, here are decompositions:

53 + 31552421 = 31552474
71 + 31552403 = 31552474
263 + 31552211 = 31552474
281 + 31552193 = 31552474
347 + 31552127 = 31552474
617 + 31551857 = 31552474
647 + 31551827 = 31552474
881 + 31551593 = 31552474

Showing the first eight; more decompositions exist.
