Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508032, here are decompositions:

5 + 31508027 = 31508032
29 + 31508003 = 31508032
41 + 31507991 = 31508032
131 + 31507901 = 31508032
239 + 31507793 = 31508032
293 + 31507739 = 31508032
449 + 31507583 = 31508032
461 + 31507571 = 31508032

Showing the first eight; more decompositions exist.
