Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702778, here are decompositions:

31 + 8702747 = 8702778
47 + 8702731 = 8702778
79 + 8702699 = 8702778
89 + 8702689 = 8702778
131 + 8702647 = 8702778
181 + 8702597 = 8702778
191 + 8702587 = 8702778
239 + 8702539 = 8702778

Showing the first eight; more decompositions exist.
