Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977728, here are decompositions:

5 + 977723 = 977728
47 + 977681 = 977728
137 + 977591 = 977728
281 + 977447 = 977728
317 + 977411 = 977728
359 + 977369 = 977728
641 + 977087 = 977728
659 + 977069 = 977728

Showing the first eight; more decompositions exist.
