Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507914, here are decompositions:

13 + 31507901 = 31507914
17 + 31507897 = 31507914
37 + 31507877 = 31507914
127 + 31507787 = 31507914
211 + 31507703 = 31507914
281 + 31507633 = 31507914
307 + 31507607 = 31507914
331 + 31507583 = 31507914

Showing the first eight; more decompositions exist.
