Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461262, here are decompositions:

71 + 31461191 = 31461262
83 + 31461179 = 31461262
89 + 31461173 = 31461262
101 + 31461161 = 31461262
113 + 31461149 = 31461262
149 + 31461113 = 31461262
251 + 31461011 = 31461262
311 + 31460951 = 31461262

Showing the first eight; more decompositions exist.
