Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547584, here are decompositions:

53 + 31547531 = 31547584
113 + 31547471 = 31547584
227 + 31547357 = 31547584
281 + 31547303 = 31547584
317 + 31547267 = 31547584
353 + 31547231 = 31547584
491 + 31547093 = 31547584
521 + 31547063 = 31547584

Showing the first eight; more decompositions exist.
