Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621614, here are decompositions:

23 + 31621591 = 31621614
53 + 31621561 = 31621614
83 + 31621531 = 31621614
97 + 31621517 = 31621614
107 + 31621507 = 31621614
113 + 31621501 = 31621614
127 + 31621487 = 31621614
137 + 31621477 = 31621614

Showing the first eight; more decompositions exist.
