Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727020, here are decompositions:

31 + 8726989 = 8727020
37 + 8726983 = 8727020
67 + 8726953 = 8727020
97 + 8726923 = 8727020
103 + 8726917 = 8727020
157 + 8726863 = 8727020
283 + 8726737 = 8727020
307 + 8726713 = 8727020

Showing the first eight; more decompositions exist.
