Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497762, here are decompositions:

5 + 31497757 = 31497762
11 + 31497751 = 31497762
41 + 31497721 = 31497762
61 + 31497701 = 31497762
83 + 31497679 = 31497762
89 + 31497673 = 31497762
193 + 31497569 = 31497762
211 + 31497551 = 31497762

Showing the first eight; more decompositions exist.
