Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31511676, here are decompositions:

23 + 31511653 = 31511676
107 + 31511569 = 31511676
127 + 31511549 = 31511676
137 + 31511539 = 31511676
139 + 31511537 = 31511676
149 + 31511527 = 31511676
173 + 31511503 = 31511676
193 + 31511483 = 31511676

Showing the first eight; more decompositions exist.
