Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028502, here are decompositions:

23 + 1028479 = 1028502
29 + 1028473 = 1028502
31 + 1028471 = 1028502
109 + 1028393 = 1028502
113 + 1028389 = 1028502
173 + 1028329 = 1028502
193 + 1028309 = 1028502
199 + 1028303 = 1028502

Showing the first eight; more decompositions exist.
