Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617900, here are decompositions:

  • 23 + 8617877 = 8617900
  • 29 + 8617871 = 8617900
  • 101 + 8617799 = 8617900
  • 113 + 8617787 = 8617900
  • 131 + 8617769 = 8617900
  • 197 + 8617703 = 8617900
  • 353 + 8617547 = 8617900
  • 461 + 8617439 = 8617900

Showing the first eight; more decompositions exist.
