Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461392, here are decompositions:

31 + 31461361 = 31461392
43 + 31461349 = 31461392
139 + 31461253 = 31461392
163 + 31461229 = 31461392
199 + 31461193 = 31461392
211 + 31461181 = 31461392
229 + 31461163 = 31461392
379 + 31461013 = 31461392

Showing the first eight; more decompositions exist.
