Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619598, here are decompositions:

37 + 31619561 = 31619598
41 + 31619557 = 31619598
67 + 31619531 = 31619598
71 + 31619527 = 31619598
79 + 31619519 = 31619598
89 + 31619509 = 31619598
97 + 31619501 = 31619598
139 + 31619459 = 31619598

Showing the first eight; more decompositions exist.
