Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612684, here are decompositions:

17 + 31612667 = 31612684
23 + 31612661 = 31612684
101 + 31612583 = 31612684
137 + 31612547 = 31612684
197 + 31612487 = 31612684
293 + 31612391 = 31612684
443 + 31612241 = 31612684
461 + 31612223 = 31612684

Showing the first eight; more decompositions exist.
