Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479676, here are decompositions:

5 + 31479671 = 31479676
29 + 31479647 = 31479676
83 + 31479593 = 31479676
257 + 31479419 = 31479676
479 + 31479197 = 31479676
593 + 31479083 = 31479676
659 + 31479017 = 31479676
719 + 31478957 = 31479676

Showing the first eight; more decompositions exist.
