Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529192, here are decompositions:

43 + 31529149 = 31529192
103 + 31529089 = 31529192
139 + 31529053 = 31529192
199 + 31528993 = 31529192
223 + 31528969 = 31529192
283 + 31528909 = 31529192
349 + 31528843 = 31529192
379 + 31528813 = 31529192

Showing the first eight; more decompositions exist.
