Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540412, here are decompositions:

73 + 31540339 = 31540412
103 + 31540309 = 31540412
151 + 31540261 = 31540412
199 + 31540213 = 31540412
223 + 31540189 = 31540412
313 + 31540099 = 31540412
349 + 31540063 = 31540412
523 + 31539889 = 31540412

Showing the first eight; more decompositions exist.
