Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977918, here are decompositions:

37 + 977881 = 977918
127 + 977791 = 977918
157 + 977761 = 977918
199 + 977719 = 977918
307 + 977611 = 977918
379 + 977539 = 977918
397 + 977521 = 977918
619 + 977299 = 977918

Showing the first eight; more decompositions exist.
