Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539330, here are decompositions:

41 + 31539289 = 31539330
47 + 31539283 = 31539330
59 + 31539271 = 31539330
89 + 31539241 = 31539330
101 + 31539229 = 31539330
139 + 31539191 = 31539330
167 + 31539163 = 31539330
241 + 31539089 = 31539330

Showing the first eight; more decompositions exist.
