Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461246, here are decompositions:

17 + 31461229 = 31461246
23 + 31461223 = 31461246
53 + 31461193 = 31461246
67 + 31461179 = 31461246
73 + 31461173 = 31461246
83 + 31461163 = 31461246
97 + 31461149 = 31461246
197 + 31461049 = 31461246

Showing the first eight; more decompositions exist.
