Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461266, here are decompositions:

13 + 31461253 = 31461266
37 + 31461229 = 31461266
43 + 31461223 = 31461266
73 + 31461193 = 31461266
103 + 31461163 = 31461266
139 + 31461127 = 31461266
229 + 31461037 = 31461266
337 + 31460929 = 31461266

Showing the first eight; more decompositions exist.
