Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461748, here are decompositions:

5 + 31461743 = 31461748
11 + 31461737 = 31461748
107 + 31461641 = 31461748
179 + 31461569 = 31461748
191 + 31461557 = 31461748
467 + 31461281 = 31461748
557 + 31461191 = 31461748
569 + 31461179 = 31461748

Showing the first eight; more decompositions exist.
