Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540244, here are decompositions:

3 + 31540241 = 31540244
31 + 31540213 = 31540244
37 + 31540207 = 31540244
97 + 31540147 = 31540244
181 + 31540063 = 31540244
277 + 31539967 = 31540244
313 + 31539931 = 31540244
487 + 31539757 = 31540244

Showing the first eight; more decompositions exist.
