Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737988, here are decompositions:

67 + 8737921 = 8737988
139 + 8737849 = 8737988
199 + 8737789 = 8737988
271 + 8737717 = 8737988
331 + 8737657 = 8737988
397 + 8737591 = 8737988
487 + 8737501 = 8737988
499 + 8737489 = 8737988

Showing the first eight; more decompositions exist.
