Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511302, here are decompositions:

41 + 31511261 = 31511302
71 + 31511231 = 31511302
89 + 31511213 = 31511302
113 + 31511189 = 31511302
131 + 31511171 = 31511302
191 + 31511111 = 31511302
233 + 31511069 = 31511302
401 + 31510901 = 31511302

Showing the first eight; more decompositions exist.
