Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458762, here are decompositions:

43 + 31458719 = 31458762
53 + 31458709 = 31458762
59 + 31458703 = 31458762
61 + 31458701 = 31458762
73 + 31458689 = 31458762
131 + 31458631 = 31458762
173 + 31458589 = 31458762
281 + 31458481 = 31458762

Showing the first eight; more decompositions exist.
