Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20774, here are decompositions:

  • 3 + 20771 = 20774
  • 31 + 20743 = 20774
  • 43 + 20731 = 20774
  • 67 + 20707 = 20774
  • 163 + 20611 = 20774
  • 181 + 20593 = 20774
  • 211 + 20563 = 20774
  • 223 + 20551 = 20774

Showing the first eight; more decompositions exist.
