Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624360, here are decompositions:

3 + 31624357 = 31624360
11 + 31624349 = 31624360
17 + 31624343 = 31624360
23 + 31624337 = 31624360
29 + 31624331 = 31624360
83 + 31624277 = 31624360
233 + 31624127 = 31624360
347 + 31624013 = 31624360

Showing the first eight; more decompositions exist.
