Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618434, here are decompositions:

11 + 31618423 = 31618434
31 + 31618403 = 31618434
73 + 31618361 = 31618434
137 + 31618297 = 31618434
223 + 31618211 = 31618434
241 + 31618193 = 31618434
271 + 31618163 = 31618434
307 + 31618127 = 31618434

Showing the first eight; more decompositions exist.
