Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496924, here are decompositions:

3 + 31496921 = 31496924
7 + 31496917 = 31496924
61 + 31496863 = 31496924
97 + 31496827 = 31496924
313 + 31496611 = 31496924
331 + 31496593 = 31496924
337 + 31496587 = 31496924
373 + 31496551 = 31496924

Showing the first eight; more decompositions exist.
