Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615856, here are decompositions:

  • 23 + 8615833 = 8615856
  • 47 + 8615809 = 8615856
  • 89 + 8615767 = 8615856
  • 107 + 8615749 = 8615856
  • 149 + 8615707 = 8615856
  • 163 + 8615693 = 8615856
  • 199 + 8615657 = 8615856
  • 233 + 8615623 = 8615856

Showing the first eight; more decompositions exist.
