Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461336, here are decompositions:

43 + 31461293 = 31461336
83 + 31461253 = 31461336
107 + 31461229 = 31461336
113 + 31461223 = 31461336
157 + 31461179 = 31461336
163 + 31461173 = 31461336
173 + 31461163 = 31461336
223 + 31461113 = 31461336

Showing the first eight; more decompositions exist.
