Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702590, here are decompositions:

3 + 8702587 = 8702590
47 + 8702543 = 8702590
101 + 8702489 = 8702590
107 + 8702483 = 8702590
131 + 8702459 = 8702590
179 + 8702411 = 8702590
257 + 8702333 = 8702590
263 + 8702327 = 8702590

Showing the first eight; more decompositions exist.
