Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501344, here are decompositions:

11 + 31501333 = 31501344
13 + 31501331 = 31501344
23 + 31501321 = 31501344
31 + 31501313 = 31501344
41 + 31501303 = 31501344
97 + 31501247 = 31501344
113 + 31501231 = 31501344
227 + 31501117 = 31501344

Showing the first eight; more decompositions exist.
