Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552354, here are decompositions:

3 + 31552351 = 31552354
83 + 31552271 = 31552354
101 + 31552253 = 31552354
227 + 31552127 = 31552354
683 + 31551671 = 31552354
761 + 31551593 = 31552354
857 + 31551497 = 31552354
941 + 31551413 = 31552354

Showing the first eight; more decompositions exist.
