Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678020, here are decompositions:

41 + 8677979 = 8678020
53 + 8677967 = 8678020
59 + 8677961 = 8678020
137 + 8677883 = 8678020
173 + 8677847 = 8678020
179 + 8677841 = 8678020
191 + 8677829 = 8678020
257 + 8677763 = 8678020

Showing the first eight; more decompositions exist.
