Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494950, here are decompositions:

7 + 31494943 = 31494950
13 + 31494937 = 31494950
31 + 31494919 = 31494950
43 + 31494907 = 31494950
181 + 31494769 = 31494950
229 + 31494721 = 31494950
271 + 31494679 = 31494950
307 + 31494643 = 31494950

Showing the first eight; more decompositions exist.
