Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612954, here are decompositions:

3 + 31612951 = 31612954
41 + 31612913 = 31612954
101 + 31612853 = 31612954
227 + 31612727 = 31612954
293 + 31612661 = 31612954
467 + 31612487 = 31612954
563 + 31612391 = 31612954
641 + 31612313 = 31612954

Showing the first eight; more decompositions exist.
