Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619996, here are decompositions:

3 + 31619993 = 31619996
7 + 31619989 = 31619996
43 + 31619953 = 31619996
127 + 31619869 = 31619996
283 + 31619713 = 31619996
313 + 31619683 = 31619996
349 + 31619647 = 31619996
379 + 31619617 = 31619996

Showing the first eight; more decompositions exist.
