Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586036, here are decompositions:

73 + 31585963 = 31586036
199 + 31585837 = 31586036
373 + 31585663 = 31586036
439 + 31585597 = 31586036
457 + 31585579 = 31586036
487 + 31585549 = 31586036
499 + 31585537 = 31586036
577 + 31585459 = 31586036

Showing the first eight; more decompositions exist.
