Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620894, here are decompositions:

47 + 8620847 = 8620894
53 + 8620841 = 8620894
137 + 8620757 = 8620894
167 + 8620727 = 8620894
173 + 8620721 = 8620894
257 + 8620637 = 8620894
263 + 8620631 = 8620894
587 + 8620307 = 8620894

Showing the first eight; more decompositions exist.
