Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612948, here are decompositions:

281 + 31612667 = 31612948
359 + 31612589 = 31612948
401 + 31612547 = 31612948
461 + 31612487 = 31612948
467 + 31612481 = 31612948
557 + 31612391 = 31612948
641 + 31612307 = 31612948
797 + 31612151 = 31612948

Showing the first eight; more decompositions exist.
