Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672020, here are decompositions:

17 + 8672003 = 8672020
29 + 8671991 = 8672020
41 + 8671979 = 8672020
53 + 8671967 = 8672020
83 + 8671937 = 8672020
101 + 8671919 = 8672020
113 + 8671907 = 8672020
251 + 8671769 = 8672020

Showing the first eight; more decompositions exist.
