Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537768, here are decompositions:

47 + 31537721 = 31537768
137 + 31537631 = 31537768
359 + 31537409 = 31537768
461 + 31537307 = 31537768
617 + 31537151 = 31537768
641 + 31537127 = 31537768
719 + 31537049 = 31537768
809 + 31536959 = 31537768

Showing the first eight; more decompositions exist.
