Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542562, here are decompositions:

3 + 31542559 = 31542562
53 + 31542509 = 31542562
83 + 31542479 = 31542562
239 + 31542323 = 31542562
281 + 31542281 = 31542562
449 + 31542113 = 31542562
479 + 31542083 = 31542562
659 + 31541903 = 31542562

Showing the first eight; more decompositions exist.
