Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747020, here are decompositions:

41 + 8746979 = 8747020
53 + 8746967 = 8747020
71 + 8746949 = 8747020
83 + 8746937 = 8747020
101 + 8746919 = 8747020
173 + 8746847 = 8747020
263 + 8746757 = 8747020
311 + 8746709 = 8747020

Showing the first eight; more decompositions exist.
