Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702142, here are decompositions:

  • 5 + 8702137 = 8702142
  • 11 + 8702131 = 8702142
  • 79 + 8702063 = 8702142
  • 151 + 8701991 = 8702142
  • 181 + 8701961 = 8702142
  • 191 + 8701951 = 8702142
  • 193 + 8701949 = 8702142
  • 269 + 8701873 = 8702142

Showing the first eight; more decompositions exist.
