Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539482, here are decompositions:

43 + 31539439 = 31539482
61 + 31539421 = 31539482
151 + 31539331 = 31539482
193 + 31539289 = 31539482
199 + 31539283 = 31539482
211 + 31539271 = 31539482
241 + 31539241 = 31539482
409 + 31539073 = 31539482

Showing the first eight; more decompositions exist.
