Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507324, here are decompositions:

3 + 31507321 = 31507324
5 + 31507319 = 31507324
41 + 31507283 = 31507324
53 + 31507271 = 31507324
113 + 31507211 = 31507324
347 + 31506977 = 31507324
503 + 31506821 = 31507324
647 + 31506677 = 31507324

Showing the first eight; more decompositions exist.
