Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516846, here are decompositions:

5 + 31516841 = 31516846
59 + 31516787 = 31516846
89 + 31516757 = 31516846
149 + 31516697 = 31516846
227 + 31516619 = 31516846
233 + 31516613 = 31516846
353 + 31516493 = 31516846
419 + 31516427 = 31516846

Showing the first eight; more decompositions exist.
