Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542762, here are decompositions:

59 + 31542703 = 31542762
103 + 31542659 = 31542762
131 + 31542631 = 31542762
149 + 31542613 = 31542762
239 + 31542523 = 31542762
283 + 31542479 = 31542762
389 + 31542373 = 31542762
421 + 31542341 = 31542762

Showing the first eight; more decompositions exist.
