Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624362, here are decompositions:

5 + 31624357 = 31624362
13 + 31624349 = 31624362
19 + 31624343 = 31624362
23 + 31624339 = 31624362
31 + 31624331 = 31624362
41 + 31624321 = 31624362
79 + 31624283 = 31624362
233 + 31624129 = 31624362

Showing the first eight; more decompositions exist.
