Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512314, here are decompositions:

7 + 31512307 = 31512314
61 + 31512253 = 31512314
103 + 31512211 = 31512314
193 + 31512121 = 31512314
277 + 31512037 = 31512314
397 + 31511917 = 31512314
433 + 31511881 = 31512314
541 + 31511773 = 31512314

Showing the first eight; more decompositions exist.
