Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494858, here are decompositions:

41 + 31494817 = 31494858
89 + 31494769 = 31494858
137 + 31494721 = 31494858
151 + 31494707 = 31494858
167 + 31494691 = 31494858
179 + 31494679 = 31494858
277 + 31494581 = 31494858
349 + 31494509 = 31494858

Showing the first eight; more decompositions exist.
