Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615940, here are decompositions:

  • 23 + 8615917 = 8615940
  • 59 + 8615881 = 8615940
  • 61 + 8615879 = 8615940
  • 107 + 8615833 = 8615940
  • 131 + 8615809 = 8615940
  • 149 + 8615791 = 8615940
  • 173 + 8615767 = 8615940
  • 191 + 8615749 = 8615940

Showing the first eight; more decompositions exist.
