Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515314, here are decompositions:

3 + 31515311 = 31515314
7 + 31515307 = 31515314
13 + 31515301 = 31515314
31 + 31515283 = 31515314
43 + 31515271 = 31515314
73 + 31515241 = 31515314
97 + 31515217 = 31515314
241 + 31515073 = 31515314

Showing the first eight; more decompositions exist.
