Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512344, here are decompositions:

13 + 31512331 = 31512344
37 + 31512307 = 31512344
223 + 31512121 = 31512344
307 + 31512037 = 31512344
463 + 31511881 = 31512344
541 + 31511803 = 31512344
571 + 31511773 = 31512344
601 + 31511743 = 31512344

Showing the first eight; more decompositions exist.
