Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726020, here are decompositions:

3 + 8726017 = 8726020
29 + 8725991 = 8726020
41 + 8725979 = 8726020
59 + 8725961 = 8726020
71 + 8725949 = 8726020
89 + 8725931 = 8726020
179 + 8725841 = 8726020
197 + 8725823 = 8726020

Showing the first eight; more decompositions exist.
