Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539374, here are decompositions:

7 + 31539367 = 31539374
37 + 31539337 = 31539374
43 + 31539331 = 31539374
103 + 31539271 = 31539374
211 + 31539163 = 31539374
313 + 31539061 = 31539374
331 + 31539043 = 31539374
367 + 31539007 = 31539374

Showing the first eight; more decompositions exist.
