Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701788, here are decompositions:

31 + 8701757 = 8701788
41 + 8701747 = 8701788
47 + 8701741 = 8701788
59 + 8701729 = 8701788
79 + 8701709 = 8701788
131 + 8701657 = 8701788
157 + 8701631 = 8701788
167 + 8701621 = 8701788

Showing the first eight; more decompositions exist.
