Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529150, here are decompositions:

43 + 31529107 = 31529150
61 + 31529089 = 31529150
97 + 31529053 = 31529150
157 + 31528993 = 31529150
181 + 31528969 = 31529150
241 + 31528909 = 31529150
307 + 31528843 = 31529150
337 + 31528813 = 31529150

Showing the first eight; more decompositions exist.
