Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737942, here are decompositions:

71 + 8737871 = 8737942
113 + 8737829 = 8737942
179 + 8737763 = 8737942
233 + 8737709 = 8737942
359 + 8737583 = 8737942
419 + 8737523 = 8737942
461 + 8737481 = 8737942
509 + 8737433 = 8737942

Showing the first eight; more decompositions exist.
