Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977648, here are decompositions:

19 + 977629 = 977648
37 + 977611 = 977648
109 + 977539 = 977648
127 + 977521 = 977648
211 + 977437 = 977648
241 + 977407 = 977648
349 + 977299 = 977648
379 + 977269 = 977648

Showing the first eight; more decompositions exist.
