Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539350, here are decompositions:

13 + 31539337 = 31539350
19 + 31539331 = 31539350
61 + 31539289 = 31539350
67 + 31539283 = 31539350
79 + 31539271 = 31539350
109 + 31539241 = 31539350
277 + 31539073 = 31539350
307 + 31539043 = 31539350

Showing the first eight; more decompositions exist.
