Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507846, here are decompositions:

23 + 31507823 = 31507846
53 + 31507793 = 31507846
59 + 31507787 = 31507846
107 + 31507739 = 31507846
137 + 31507709 = 31507846
179 + 31507667 = 31507846
239 + 31507607 = 31507846
263 + 31507583 = 31507846

Showing the first eight; more decompositions exist.
