Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494762, here are decompositions:

41 + 31494721 = 31494762
71 + 31494691 = 31494762
73 + 31494689 = 31494762
83 + 31494679 = 31494762
151 + 31494611 = 31494762
179 + 31494583 = 31494762
181 + 31494581 = 31494762
283 + 31494479 = 31494762

Showing the first eight; more decompositions exist.
