Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619792, here are decompositions:

3 + 31619789 = 31619792
31 + 31619761 = 31619792
79 + 31619713 = 31619792
109 + 31619683 = 31619792
181 + 31619611 = 31619792
271 + 31619521 = 31619792
283 + 31619509 = 31619792
433 + 31619359 = 31619792

Showing the first eight; more decompositions exist.
