Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460762, here are decompositions:

19 + 31460743 = 31460762
61 + 31460701 = 31460762
181 + 31460581 = 31460762
211 + 31460551 = 31460762
271 + 31460491 = 31460762
331 + 31460431 = 31460762
349 + 31460413 = 31460762
433 + 31460329 = 31460762

Showing the first eight; more decompositions exist.
