Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539206, here are decompositions:

43 + 31539163 = 31539206
163 + 31539043 = 31539206
199 + 31539007 = 31539206
379 + 31538827 = 31539206
463 + 31538743 = 31539206
487 + 31538719 = 31539206
577 + 31538629 = 31539206
733 + 31538473 = 31539206

Showing the first eight; more decompositions exist.
