Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514048, here are decompositions:

61 + 31513987 = 31514048
157 + 31513891 = 31514048
199 + 31513849 = 31514048
229 + 31513819 = 31514048
487 + 31513561 = 31514048
739 + 31513309 = 31514048
829 + 31513219 = 31514048
991 + 31513057 = 31514048

Showing the first eight; more decompositions exist.
