Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508004, here are decompositions:

13 + 31507991 = 31508004
23 + 31507981 = 31508004
53 + 31507951 = 31508004
83 + 31507921 = 31508004
103 + 31507901 = 31508004
107 + 31507897 = 31508004
127 + 31507877 = 31508004
167 + 31507837 = 31508004

Showing the first eight; more decompositions exist.
