Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606946, here are decompositions:

3 + 31606943 = 31606946
43 + 31606903 = 31606946
67 + 31606879 = 31606946
193 + 31606753 = 31606946
367 + 31606579 = 31606946
409 + 31606537 = 31606946
523 + 31606423 = 31606946
577 + 31606369 = 31606946

Showing the first eight; more decompositions exist.
