Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514242, here are decompositions:

3 + 31514239 = 31514242
83 + 31514159 = 31514242
449 + 31513793 = 31514242
503 + 31513739 = 31514242
521 + 31513721 = 31514242
839 + 31513403 = 31514242
911 + 31513331 = 31514242
983 + 31513259 = 31514242

Showing the first eight; more decompositions exist.
