Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506676, here are decompositions:

107 + 31506569 = 31506676
197 + 31506479 = 31506676
233 + 31506443 = 31506676
239 + 31506437 = 31506676
317 + 31506359 = 31506676
503 + 31506173 = 31506676
557 + 31506119 = 31506676
647 + 31506029 = 31506676

Showing the first eight; more decompositions exist.
