Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702390, here are decompositions:

3 + 8702387 = 8702390
19 + 8702371 = 8702390
31 + 8702359 = 8702390
61 + 8702329 = 8702390
79 + 8702311 = 8702390
139 + 8702251 = 8702390
211 + 8702179 = 8702390
241 + 8702149 = 8702390

Showing the first eight; more decompositions exist.
