Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736220, here are decompositions:

  • 11 + 8736209 = 8736220
  • 29 + 8736191 = 8736220
  • 41 + 8736179 = 8736220
  • 47 + 8736173 = 8736220
  • 131 + 8736089 = 8736220
  • 179 + 8736041 = 8736220
  • 359 + 8735861 = 8736220
  • 431 + 8735789 = 8736220

Showing the first eight; more decompositions exist.
