Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977690, here are decompositions:

19 + 977671 = 977690
61 + 977629 = 977690
79 + 977611 = 977690
97 + 977593 = 977690
151 + 977539 = 977690
277 + 977413 = 977690
283 + 977407 = 977690
331 + 977359 = 977690

Showing the first eight; more decompositions exist.
