Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612964, here are decompositions:

3 + 31612961 = 31612964
13 + 31612951 = 31612964
73 + 31612891 = 31612964
211 + 31612753 = 31612964
337 + 31612627 = 31612964
367 + 31612597 = 31612964
433 + 31612531 = 31612964
541 + 31612423 = 31612964

Showing the first eight; more decompositions exist.
