Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528034, here are decompositions:

37 + 31527997 = 31528034
67 + 31527967 = 31528034
103 + 31527931 = 31528034
331 + 31527703 = 31528034
337 + 31527697 = 31528034
457 + 31527577 = 31528034
691 + 31527343 = 31528034
757 + 31527277 = 31528034

Showing the first eight; more decompositions exist.
