Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677942, here are decompositions:

59 + 8677883 = 8677942
101 + 8677841 = 8677942
113 + 8677829 = 8677942
179 + 8677763 = 8677942
389 + 8677553 = 8677942
431 + 8677511 = 8677942
461 + 8677481 = 8677942
599 + 8677343 = 8677942

Showing the first eight; more decompositions exist.
