Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617932, here are decompositions:

43 + 31617889 = 31617932
61 + 31617871 = 31617932
79 + 31617853 = 31617932
349 + 31617583 = 31617932
373 + 31617559 = 31617932
439 + 31617493 = 31617932
523 + 31617409 = 31617932
571 + 31617361 = 31617932

Showing the first eight; more decompositions exist.
