Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506484, here are decompositions:

5 + 31506479 = 31506484
41 + 31506443 = 31506484
47 + 31506437 = 31506484
131 + 31506353 = 31506484
173 + 31506311 = 31506484
311 + 31506173 = 31506484
491 + 31505993 = 31506484
557 + 31505927 = 31506484

Showing the first eight; more decompositions exist.
