Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496680, here are decompositions:

3 + 31496677 = 31496680
11 + 31496669 = 31496680
107 + 31496573 = 31496680
113 + 31496567 = 31496680
191 + 31496489 = 31496680
239 + 31496441 = 31496680
251 + 31496429 = 31496680
263 + 31496417 = 31496680

Showing the first eight; more decompositions exist.
