Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8624090, here are decompositions:

31 + 8624059 = 8624090
67 + 8624023 = 8624090
73 + 8624017 = 8624090
127 + 8623963 = 8624090
151 + 8623939 = 8624090
193 + 8623897 = 8624090
283 + 8623807 = 8624090
373 + 8623717 = 8624090

Showing the first eight; more decompositions exist.
