Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540256, here are decompositions:

43 + 31540213 = 31540256
67 + 31540189 = 31540256
109 + 31540147 = 31540256
157 + 31540099 = 31540256
193 + 31540063 = 31540256
367 + 31539889 = 31540256
439 + 31539817 = 31540256
499 + 31539757 = 31540256

Showing the first eight; more decompositions exist.
