Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977544, here are decompositions:

5 + 977539 = 977544
23 + 977521 = 977544
31 + 977513 = 977544
37 + 977507 = 977544
97 + 977447 = 977544
107 + 977437 = 977544
131 + 977413 = 977544
137 + 977407 = 977544

Showing the first eight; more decompositions exist.
