Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496690, here are decompositions:

13 + 31496677 = 31496690
19 + 31496671 = 31496690
79 + 31496611 = 31496690
97 + 31496593 = 31496690
103 + 31496587 = 31496690
139 + 31496551 = 31496690
151 + 31496539 = 31496690
241 + 31496449 = 31496690

Showing the first eight; more decompositions exist.
