Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87222, here are decompositions:

  • 11 + 87211 = 87222
  • 41 + 87181 = 87222
  • 43 + 87179 = 87222
  • 71 + 87151 = 87222
  • 73 + 87149 = 87222
  • 89 + 87133 = 87222
  • 101 + 87121 = 87222
  • 103 + 87119 = 87222

Showing the first eight; more decompositions exist.
