Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977518, here are decompositions:

5 + 977513 = 977518
11 + 977507 = 977518
71 + 977447 = 977518
107 + 977411 = 977518
149 + 977369 = 977518
167 + 977351 = 977518
431 + 977087 = 977518
449 + 977069 = 977518

Showing the first eight; more decompositions exist.
