Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619708, here are decompositions:

61 + 31619647 = 31619708
97 + 31619611 = 31619708
151 + 31619557 = 31619708
181 + 31619527 = 31619708
199 + 31619509 = 31619708
349 + 31619359 = 31619708
397 + 31619311 = 31619708
499 + 31619209 = 31619708

Showing the first eight; more decompositions exist.
