Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701782, here are decompositions:

41 + 8701741 = 8701782
53 + 8701729 = 8701782
59 + 8701723 = 8701782
73 + 8701709 = 8701782
79 + 8701703 = 8701782
139 + 8701643 = 8701782
151 + 8701631 = 8701782
211 + 8701571 = 8701782

Showing the first eight; more decompositions exist.
