Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603556, here are decompositions:

23 + 8603533 = 8603556
47 + 8603509 = 8603556
67 + 8603489 = 8603556
79 + 8603477 = 8603556
89 + 8603467 = 8603556
103 + 8603453 = 8603556
127 + 8603429 = 8603556
149 + 8603407 = 8603556

Showing the first eight; more decompositions exist.
