Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31490024, here are decompositions:

61 + 31489963 = 31490024
151 + 31489873 = 31490024
271 + 31489753 = 31490024
277 + 31489747 = 31490024
373 + 31489651 = 31490024
607 + 31489417 = 31490024
613 + 31489411 = 31490024
661 + 31489363 = 31490024

Showing the first eight; more decompositions exist.
