Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702620, here are decompositions:

23 + 8702597 = 8702620
29 + 8702591 = 8702620
131 + 8702489 = 8702620
137 + 8702483 = 8702620
233 + 8702387 = 8702620
293 + 8702327 = 8702620
389 + 8702231 = 8702620
431 + 8702189 = 8702620

Showing the first eight; more decompositions exist.
