Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627988, here are decompositions:

  • 11 + 8627977 = 8627988
  • 41 + 8627947 = 8627988
  • 79 + 8627909 = 8627988
  • 137 + 8627851 = 8627988
  • 179 + 8627809 = 8627988
  • 181 + 8627807 = 8627988
  • 211 + 8627777 = 8627988
  • 307 + 8627681 = 8627988

Showing the first eight; more decompositions exist.
