Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977638, here are decompositions:

29 + 977609 = 977638
47 + 977591 = 977638
71 + 977567 = 977638
131 + 977507 = 977638
191 + 977447 = 977638
227 + 977411 = 977638
269 + 977369 = 977638
281 + 977357 = 977638

Showing the first eight; more decompositions exist.
