Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602490, here are decompositions:

3 + 8602487 = 8602490
19 + 8602471 = 8602490
73 + 8602417 = 8602490
109 + 8602381 = 8602490
151 + 8602339 = 8602490
271 + 8602219 = 8602490
277 + 8602213 = 8602490
313 + 8602177 = 8602490

Showing the first eight; more decompositions exist.
