Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707490, here are decompositions:

13 + 8707477 = 8707490
61 + 8707429 = 8707490
97 + 8707393 = 8707490
139 + 8707351 = 8707490
157 + 8707333 = 8707490
163 + 8707327 = 8707490
271 + 8707219 = 8707490
283 + 8707207 = 8707490

Showing the first eight; more decompositions exist.
