Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461326, here are decompositions:

73 + 31461253 = 31461326
97 + 31461229 = 31461326
103 + 31461223 = 31461326
163 + 31461163 = 31461326
199 + 31461127 = 31461326
277 + 31461049 = 31461326
313 + 31461013 = 31461326
349 + 31460977 = 31461326

Showing the first eight; more decompositions exist.
