Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461166, here are decompositions:

3 + 31461163 = 31461166
5 + 31461161 = 31461166
17 + 31461149 = 31461166
53 + 31461113 = 31461166
239 + 31460927 = 31461166
293 + 31460873 = 31461166
383 + 31460783 = 31461166
449 + 31460717 = 31461166

Showing the first eight; more decompositions exist.
