Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624324, here are decompositions:

3 + 31624321 = 31624324
41 + 31624283 = 31624324
47 + 31624277 = 31624324
107 + 31624217 = 31624324
197 + 31624127 = 31624324
311 + 31624013 = 31624324
353 + 31623971 = 31624324
467 + 31623857 = 31624324

Showing the first eight; more decompositions exist.
