Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702878, here are decompositions:

59 + 8702819 = 8702878
101 + 8702777 = 8702878
131 + 8702747 = 8702878
179 + 8702699 = 8702878
281 + 8702597 = 8702878
389 + 8702489 = 8702878
419 + 8702459 = 8702878
467 + 8702411 = 8702878

Showing the first eight; more decompositions exist.
