Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511344, here are decompositions:

3 + 31511341 = 31511344
17 + 31511327 = 31511344
23 + 31511321 = 31511344
83 + 31511261 = 31511344
113 + 31511231 = 31511344
131 + 31511213 = 31511344
173 + 31511171 = 31511344
197 + 31511147 = 31511344

Showing the first eight; more decompositions exist.
