Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618464, here are decompositions:

23 + 31618441 = 31618464
41 + 31618423 = 31618464
61 + 31618403 = 31618464
103 + 31618361 = 31618464
167 + 31618297 = 31618464
233 + 31618231 = 31618464
271 + 31618193 = 31618464
277 + 31618187 = 31618464

Showing the first eight; more decompositions exist.
