Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540274, here are decompositions:

13 + 31540261 = 31540274
61 + 31540213 = 31540274
67 + 31540207 = 31540274
127 + 31540147 = 31540274
151 + 31540123 = 31540274
211 + 31540063 = 31540274
307 + 31539967 = 31540274
373 + 31539901 = 31540274

Showing the first eight; more decompositions exist.
