Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539354, here are decompositions:

5 + 31539349 = 31539354
17 + 31539337 = 31539354
23 + 31539331 = 31539354
71 + 31539283 = 31539354
83 + 31539271 = 31539354
113 + 31539241 = 31539354
163 + 31539191 = 31539354
191 + 31539163 = 31539354

Showing the first eight; more decompositions exist.
