Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474314, here are decompositions:

7 + 31474307 = 31474314
13 + 31474301 = 31474314
23 + 31474291 = 31474314
61 + 31474253 = 31474314
97 + 31474217 = 31474314
101 + 31474213 = 31474314
173 + 31474141 = 31474314
241 + 31474073 = 31474314

Showing the first eight; more decompositions exist.
