Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486948, here are decompositions:

89 + 31486859 = 31486948
179 + 31486769 = 31486948
197 + 31486751 = 31486948
239 + 31486709 = 31486948
419 + 31486529 = 31486948
491 + 31486457 = 31486948
557 + 31486391 = 31486948
599 + 31486349 = 31486948

Showing the first eight; more decompositions exist.
