Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508044, here are decompositions:

5 + 31508039 = 31508044
17 + 31508027 = 31508044
41 + 31508003 = 31508044
53 + 31507991 = 31508044
131 + 31507913 = 31508044
167 + 31507877 = 31508044
251 + 31507793 = 31508044
257 + 31507787 = 31508044

Showing the first eight; more decompositions exist.
