Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977870, here are decompositions:

67 + 977803 = 977870
79 + 977791 = 977870
109 + 977761 = 977870
151 + 977719 = 977870
199 + 977671 = 977870
241 + 977629 = 977870
277 + 977593 = 977870
331 + 977539 = 977870

Showing the first eight; more decompositions exist.
