Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748020, here are decompositions:

3 + 8748017 = 8748020
19 + 8748001 = 8748020
79 + 8747941 = 8748020
103 + 8747917 = 8748020
157 + 8747863 = 8748020
163 + 8747857 = 8748020
277 + 8747743 = 8748020
283 + 8747737 = 8748020

Showing the first eight; more decompositions exist.
