Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624392, here are decompositions:

5 + 31624387 = 31624392
29 + 31624363 = 31624392
43 + 31624349 = 31624392
53 + 31624339 = 31624392
61 + 31624331 = 31624392
71 + 31624321 = 31624392
109 + 31624283 = 31624392
251 + 31624141 = 31624392

Showing the first eight; more decompositions exist.
