Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977906, here are decompositions:

103 + 977803 = 977906
277 + 977629 = 977906
313 + 977593 = 977906
367 + 977539 = 977906
499 + 977407 = 977906
547 + 977359 = 977906
607 + 977299 = 977906
673 + 977233 = 977906

Showing the first eight; more decompositions exist.
