Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977520, here are decompositions:

7 + 977513 = 977520
13 + 977507 = 977520
73 + 977447 = 977520
83 + 977437 = 977520
107 + 977413 = 977520
109 + 977411 = 977520
113 + 977407 = 977520
151 + 977369 = 977520

Showing the first eight; more decompositions exist.
