Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496954, here are decompositions:

7 + 31496947 = 31496954
37 + 31496917 = 31496954
127 + 31496827 = 31496954
163 + 31496791 = 31496954
277 + 31496677 = 31496954
283 + 31496671 = 31496954
367 + 31496587 = 31496954
661 + 31496293 = 31496954

Showing the first eight; more decompositions exist.
