Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702490, here are decompositions:

7 + 8702483 = 8702490
31 + 8702459 = 8702490
59 + 8702431 = 8702490
79 + 8702411 = 8702490
103 + 8702387 = 8702490
131 + 8702359 = 8702490
149 + 8702341 = 8702490
157 + 8702333 = 8702490

Showing the first eight; more decompositions exist.
