Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516464, here are decompositions:

37 + 31516427 = 31516464
41 + 31516423 = 31516464
53 + 31516411 = 31516464
103 + 31516361 = 31516464
107 + 31516357 = 31516464
131 + 31516333 = 31516464
137 + 31516327 = 31516464
167 + 31516297 = 31516464

Showing the first eight; more decompositions exist.
