Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539434, here are decompositions:

13 + 31539421 = 31539434
67 + 31539367 = 31539434
97 + 31539337 = 31539434
103 + 31539331 = 31539434
151 + 31539283 = 31539434
163 + 31539271 = 31539434
193 + 31539241 = 31539434
271 + 31539163 = 31539434

Showing the first eight; more decompositions exist.
