Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620846, here are decompositions:

5 + 8620841 = 8620846
89 + 8620757 = 8620846
107 + 8620739 = 8620846
173 + 8620673 = 8620846
257 + 8620589 = 8620846
293 + 8620553 = 8620846
317 + 8620529 = 8620846
347 + 8620499 = 8620846

Showing the first eight; more decompositions exist.
