Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546762, here are decompositions:

3 + 31546759 = 31546762
41 + 31546721 = 31546762
53 + 31546709 = 31546762
101 + 31546661 = 31546762
179 + 31546583 = 31546762
293 + 31546469 = 31546762
311 + 31546451 = 31546762
461 + 31546301 = 31546762

Showing the first eight; more decompositions exist.
