Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977644, here are decompositions:

53 + 977591 = 977644
131 + 977513 = 977644
137 + 977507 = 977644
197 + 977447 = 977644
233 + 977411 = 977644
281 + 977363 = 977644
293 + 977351 = 977644
401 + 977243 = 977644

Showing the first eight; more decompositions exist.
