Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739988, here are decompositions:

  • 71 + 8739917 = 8739988
  • 137 + 8739851 = 8739988
  • 167 + 8739821 = 8739988
  • 239 + 8739749 = 8739988
  • 317 + 8739671 = 8739988
  • 557 + 8739431 = 8739988
  • 599 + 8739389 = 8739988
  • 821 + 8739167 = 8739988

Showing the first eight; more decompositions exist.
