Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737990, here are decompositions:

11 + 8737979 = 8737990
47 + 8737943 = 8737990
227 + 8737763 = 8737990
281 + 8737709 = 8737990
293 + 8737697 = 8737990
419 + 8737571 = 8737990
461 + 8737529 = 8737990
467 + 8737523 = 8737990

Showing the first eight; more decompositions exist.
