Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506116, here are decompositions:

13 + 31506103 = 31506116
127 + 31505989 = 31506116
157 + 31505959 = 31506116
193 + 31505923 = 31506116
307 + 31505809 = 31506116
349 + 31505767 = 31506116
379 + 31505737 = 31506116
457 + 31505659 = 31506116

Showing the first eight; more decompositions exist.
