Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91088, here are decompositions:

  • 7 + 91081 = 91088
  • 79 + 91009 = 91088
  • 157 + 90931 = 91088
  • 181 + 90907 = 91088
  • 241 + 90847 = 91088
  • 379 + 90709 = 91088
  • 409 + 90679 = 91088
  • 457 + 90631 = 91088

Showing the first eight; more decompositions exist.
