Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702426, here are decompositions:

67 + 8702359 = 8702426
97 + 8702329 = 8702426
277 + 8702149 = 8702426
613 + 8701813 = 8702426
769 + 8701657 = 8702426
907 + 8701519 = 8702426
919 + 8701507 = 8702426
937 + 8701489 = 8702426

Showing the first eight; more decompositions exist.
