Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461396, here are decompositions:

47 + 31461349 = 31461396
53 + 31461343 = 31461396
103 + 31461293 = 31461396
167 + 31461229 = 31461396
173 + 31461223 = 31461396
223 + 31461173 = 31461396
233 + 31461163 = 31461396
269 + 31461127 = 31461396

Showing the first eight; more decompositions exist.
