Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539030, here are decompositions:

23 + 31539007 = 31539030
43 + 31538987 = 31539030
79 + 31538951 = 31539030
223 + 31538807 = 31539030
241 + 31538789 = 31539030
251 + 31538779 = 31539030
277 + 31538753 = 31539030
311 + 31538719 = 31539030

Showing the first eight; more decompositions exist.
