Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539266, here are decompositions:

37 + 31539229 = 31539266
103 + 31539163 = 31539266
193 + 31539073 = 31539266
223 + 31539043 = 31539266
379 + 31538887 = 31539266
439 + 31538827 = 31539266
487 + 31538779 = 31539266
523 + 31538743 = 31539266

Showing the first eight; more decompositions exist.
