Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540214, here are decompositions:

3 + 31540211 = 31540214
7 + 31540207 = 31540214
67 + 31540147 = 31540214
151 + 31540063 = 31540214
283 + 31539931 = 31540214
313 + 31539901 = 31540214
397 + 31539817 = 31540214
457 + 31539757 = 31540214

Showing the first eight; more decompositions exist.
