Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462690, here are decompositions:

41 + 31462649 = 31462690
101 + 31462589 = 31462690
107 + 31462583 = 31462690
113 + 31462577 = 31462690
137 + 31462553 = 31462690
239 + 31462451 = 31462690
251 + 31462439 = 31462690
257 + 31462433 = 31462690

Showing the first eight; more decompositions exist.
