Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552628, here are decompositions:

7 + 31552621 = 31552628
139 + 31552489 = 31552628
199 + 31552429 = 31552628
241 + 31552387 = 31552628
277 + 31552351 = 31552628
421 + 31552207 = 31552628
571 + 31552057 = 31552628
631 + 31551997 = 31552628

Showing the first eight; more decompositions exist.
