Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507762, here are decompositions:

23 + 31507739 = 31507762
53 + 31507709 = 31507762
59 + 31507703 = 31507762
101 + 31507661 = 31507762
179 + 31507583 = 31507762
191 + 31507571 = 31507762
239 + 31507523 = 31507762
359 + 31507403 = 31507762

Showing the first eight; more decompositions exist.
