Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719242, here are decompositions:

  • 19 + 8719223 = 8719242
  • 23 + 8719219 = 8719242
  • 29 + 8719213 = 8719242
  • 31 + 8719211 = 8719242
  • 43 + 8719199 = 8719242
  • 79 + 8719163 = 8719242
  • 83 + 8719159 = 8719242
  • 101 + 8719141 = 8719242

Showing the first eight; more decompositions exist.
