Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977810, here are decompositions:

7 + 977803 = 977810
19 + 977791 = 977810
139 + 977671 = 977810
181 + 977629 = 977810
199 + 977611 = 977810
271 + 977539 = 977810
373 + 977437 = 977810
397 + 977413 = 977810

Showing the first eight; more decompositions exist.
