Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539344, here are decompositions:

7 + 31539337 = 31539344
13 + 31539331 = 31539344
61 + 31539283 = 31539344
73 + 31539271 = 31539344
103 + 31539241 = 31539344
181 + 31539163 = 31539344
271 + 31539073 = 31539344
283 + 31539061 = 31539344

Showing the first eight; more decompositions exist.
