Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539326, here are decompositions:

37 + 31539289 = 31539326
43 + 31539283 = 31539326
97 + 31539229 = 31539326
163 + 31539163 = 31539326
283 + 31539043 = 31539326
439 + 31538887 = 31539326
499 + 31538827 = 31539326
547 + 31538779 = 31539326

Showing the first eight; more decompositions exist.
