Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461052, here are decompositions:

3 + 31461049 = 31461052
5 + 31461047 = 31461052
41 + 31461011 = 31461052
101 + 31460951 = 31461052
173 + 31460879 = 31461052
179 + 31460873 = 31461052
269 + 31460783 = 31461052
443 + 31460609 = 31461052

Showing the first eight; more decompositions exist.
