Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977858, here are decompositions:

67 + 977791 = 977858
97 + 977761 = 977858
139 + 977719 = 977858
229 + 977629 = 977858
337 + 977521 = 977858
421 + 977437 = 977858
499 + 977359 = 977858
601 + 977257 = 977858

Showing the first eight; more decompositions exist.
