Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462762, here are decompositions:

3 + 31462759 = 31462762
5 + 31462757 = 31462762
11 + 31462751 = 31462762
113 + 31462649 = 31462762
173 + 31462589 = 31462762
179 + 31462583 = 31462762
281 + 31462481 = 31462762
311 + 31462451 = 31462762

Showing the first eight; more decompositions exist.
