Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757020, here are decompositions:

7 + 8757013 = 8757020
37 + 8756983 = 8757020
61 + 8756959 = 8757020
67 + 8756953 = 8757020
73 + 8756947 = 8757020
79 + 8756941 = 8757020
313 + 8756707 = 8757020
331 + 8756689 = 8757020

Showing the first eight; more decompositions exist.
