Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552340, here are decompositions:

31 + 31552309 = 31552340
37 + 31552303 = 31552340
103 + 31552237 = 31552340
271 + 31552069 = 31552340
283 + 31552057 = 31552340
307 + 31552033 = 31552340
439 + 31551901 = 31552340
487 + 31551853 = 31552340

Showing the first eight; more decompositions exist.
