Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31557054, here are decompositions:

31 + 31557023 = 31557054
41 + 31557013 = 31557054
43 + 31557011 = 31557054
47 + 31557007 = 31557054
97 + 31556957 = 31557054
131 + 31556923 = 31557054
197 + 31556857 = 31557054
227 + 31556827 = 31557054

Showing the first eight; more decompositions exist.
