Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461462, here are decompositions:

5 + 31461457 = 31461462
59 + 31461403 = 31461462
101 + 31461361 = 31461462
113 + 31461349 = 31461462
181 + 31461281 = 31461462
233 + 31461229 = 31461462
239 + 31461223 = 31461462
269 + 31461193 = 31461462

Showing the first eight; more decompositions exist.
