Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737828, here are decompositions:

131 + 8737697 = 8737828
251 + 8737577 = 8737828
257 + 8737571 = 8737828
347 + 8737481 = 8737828
401 + 8737427 = 8737828
479 + 8737349 = 8737828
557 + 8737271 = 8737828
761 + 8737067 = 8737828

Showing the first eight; more decompositions exist.
