Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31510848, here are decompositions:

37 + 31510811 = 31510848
59 + 31510789 = 31510848
67 + 31510781 = 31510848
79 + 31510769 = 31510848
157 + 31510691 = 31510848
167 + 31510681 = 31510848
191 + 31510657 = 31510848
307 + 31510541 = 31510848

Showing the first eight; more decompositions exist.
