Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018502, here are decompositions:

13 + 1018489 = 1018502
31 + 1018471 = 1018502
73 + 1018429 = 1018502
193 + 1018309 = 1018502
211 + 1018291 = 1018502
379 + 1018123 = 1018502
613 + 1017889 = 1018502
643 + 1017859 = 1018502

Showing the first eight; more decompositions exist.
