Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540334, here are decompositions:

37 + 31540297 = 31540334
73 + 31540261 = 31540334
127 + 31540207 = 31540334
211 + 31540123 = 31540334
271 + 31540063 = 31540334
367 + 31539967 = 31540334
433 + 31539901 = 31540334
571 + 31539763 = 31540334

Showing the first eight; more decompositions exist.
