Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461766, here are decompositions:

3 + 31461763 = 31461766
5 + 31461761 = 31461766
23 + 31461743 = 31461766
29 + 31461737 = 31461766
113 + 31461653 = 31461766
197 + 31461569 = 31461766
233 + 31461533 = 31461766
353 + 31461413 = 31461766

Showing the first eight; more decompositions exist.
