Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80906, here are decompositions:

  • 43 + 80863 = 80906
  • 73 + 80833 = 80906
  • 97 + 80809 = 80906
  • 103 + 80803 = 80906
  • 127 + 80779 = 80906
  • 157 + 80749 = 80906
  • 193 + 80713 = 80906
  • 223 + 80683 = 80906

Showing the first eight; more decompositions exist.
