Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461458, here are decompositions:

31 + 31461427 = 31461458
97 + 31461361 = 31461458
109 + 31461349 = 31461458
157 + 31461301 = 31461458
229 + 31461229 = 31461458
277 + 31461181 = 31461458
331 + 31461127 = 31461458
409 + 31461049 = 31461458

Showing the first eight; more decompositions exist.
