Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977816, here are decompositions:

3 + 977813 = 977816
13 + 977803 = 977816
97 + 977719 = 977816
223 + 977593 = 977816
277 + 977539 = 977816
379 + 977437 = 977816
409 + 977407 = 977816
457 + 977359 = 977816

Showing the first eight; more decompositions exist.
