Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977556, here are decompositions:

17 + 977539 = 977556
43 + 977513 = 977556
109 + 977447 = 977556
149 + 977407 = 977556
193 + 977363 = 977556
197 + 977359 = 977556
199 + 977357 = 977556
233 + 977323 = 977556

Showing the first eight; more decompositions exist.
