Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552534, here are decompositions:

47 + 31552487 = 31552534
113 + 31552421 = 31552534
131 + 31552403 = 31552534
263 + 31552271 = 31552534
281 + 31552253 = 31552534
557 + 31551977 = 31552534
593 + 31551941 = 31552534
677 + 31551857 = 31552534

Showing the first eight; more decompositions exist.
