Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737642, here are decompositions:

59 + 8737583 = 8737642
71 + 8737571 = 8737642
113 + 8737529 = 8737642
269 + 8737373 = 8737642
293 + 8737349 = 8737642
443 + 8737199 = 8737642
449 + 8737193 = 8737642
503 + 8737139 = 8737642

Showing the first eight; more decompositions exist.
