Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508024, here are decompositions:

7 + 31508017 = 31508024
43 + 31507981 = 31508024
73 + 31507951 = 31508024
103 + 31507921 = 31508024
127 + 31507897 = 31508024
271 + 31507753 = 31508024
433 + 31507591 = 31508024
463 + 31507561 = 31508024

Showing the first eight; more decompositions exist.
