Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528706, here are decompositions:

37 + 31528669 = 31528706
73 + 31528633 = 31528706
127 + 31528579 = 31528706
379 + 31528327 = 31528706
439 + 31528267 = 31528706
499 + 31528207 = 31528706
613 + 31528093 = 31528706
709 + 31527997 = 31528706

Showing the first eight; more decompositions exist.
