Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528724, here are decompositions:

103 + 31528621 = 31528724
151 + 31528573 = 31528724
193 + 31528531 = 31528724
223 + 31528501 = 31528724
277 + 31528447 = 31528724
397 + 31528327 = 31528724
433 + 31528291 = 31528724
457 + 31528267 = 31528724

Showing the first eight; more decompositions exist.
