Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90806, here are decompositions:

  • 3 + 90803 = 90806
  • 13 + 90793 = 90806
  • 19 + 90787 = 90806
  • 97 + 90709 = 90806
  • 103 + 90703 = 90806
  • 109 + 90697 = 90806
  • 127 + 90679 = 90806
  • 223 + 90583 = 90806

Showing the first eight; more decompositions exist.
