Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477762, here are decompositions:

3 + 31477759 = 31477762
11 + 31477751 = 31477762
179 + 31477583 = 31477762
191 + 31477571 = 31477762
383 + 31477379 = 31477762
461 + 31477301 = 31477762
599 + 31477163 = 31477762
683 + 31477079 = 31477762

Showing the first eight; more decompositions exist.
