Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539662, here are decompositions:

3 + 31539659 = 31539662
13 + 31539649 = 31539662
19 + 31539643 = 31539662
79 + 31539583 = 31539662
139 + 31539523 = 31539662
163 + 31539499 = 31539662
223 + 31539439 = 31539662
241 + 31539421 = 31539662

Showing the first eight; more decompositions exist.
