Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539338, here are decompositions:

7 + 31539331 = 31539338
67 + 31539271 = 31539338
97 + 31539241 = 31539338
109 + 31539229 = 31539338
277 + 31539061 = 31539338
331 + 31539007 = 31539338
619 + 31538719 = 31539338
709 + 31538629 = 31539338

Showing the first eight; more decompositions exist.
