Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582094, here are decompositions:

67 + 31582027 = 31582094
73 + 31582021 = 31582094
97 + 31581997 = 31582094
211 + 31581883 = 31582094
277 + 31581817 = 31582094
307 + 31581787 = 31582094
421 + 31581673 = 31582094
547 + 31581547 = 31582094

Showing the first eight; more decompositions exist.
