Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977828, here are decompositions:

37 + 977791 = 977828
67 + 977761 = 977828
109 + 977719 = 977828
157 + 977671 = 977828
199 + 977629 = 977828
307 + 977521 = 977828
421 + 977407 = 977828
571 + 977257 = 977828

Showing the first eight; more decompositions exist.
