Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540826, here are decompositions:

3 + 31540823 = 31540826
13 + 31540813 = 31540826
43 + 31540783 = 31540826
103 + 31540723 = 31540826
127 + 31540699 = 31540826
157 + 31540669 = 31540826
337 + 31540489 = 31540826
409 + 31540417 = 31540826

Showing the first eight; more decompositions exist.
