Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619670, here are decompositions:

23 + 31619647 = 31619670
53 + 31619617 = 31619670
59 + 31619611 = 31619670
67 + 31619603 = 31619670
109 + 31619561 = 31619670
113 + 31619557 = 31619670
127 + 31619543 = 31619670
139 + 31619531 = 31619670

Showing the first eight; more decompositions exist.
