Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470762, here are decompositions:

41 + 31470721 = 31470762
53 + 31470709 = 31470762
61 + 31470701 = 31470762
101 + 31470661 = 31470762
109 + 31470653 = 31470762
139 + 31470623 = 31470762
181 + 31470581 = 31470762
199 + 31470563 = 31470762

Showing the first eight; more decompositions exist.
