Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76890, here are decompositions:

  • 7 + 76883 = 76890
  • 17 + 76873 = 76890
  • 19 + 76871 = 76890
  • 43 + 76847 = 76890
  • 53 + 76837 = 76890
  • 59 + 76831 = 76890
  • 61 + 76829 = 76890
  • 71 + 76819 = 76890

Showing the first eight; more decompositions exist.
