Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611654, here are decompositions:

7 + 31611647 = 31611654
13 + 31611641 = 31611654
37 + 31611617 = 31611654
47 + 31611607 = 31611654
71 + 31611583 = 31611654
73 + 31611581 = 31611654
101 + 31611553 = 31611654
127 + 31611527 = 31611654

Showing the first eight; more decompositions exist.
