Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547056, here are decompositions:

17 + 31547039 = 31547056
53 + 31547003 = 31547056
59 + 31546997 = 31547056
239 + 31546817 = 31547056
257 + 31546799 = 31547056
347 + 31546709 = 31547056
419 + 31546637 = 31547056
503 + 31546553 = 31547056

Showing the first eight; more decompositions exist.
