Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511362, here are decompositions:

41 + 31511321 = 31511362
101 + 31511261 = 31511362
131 + 31511231 = 31511362
149 + 31511213 = 31511362
173 + 31511189 = 31511362
191 + 31511171 = 31511362
251 + 31511111 = 31511362
293 + 31511069 = 31511362

Showing the first eight; more decompositions exist.
