Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702372, here are decompositions:

  • 13 + 8702359 = 8702372
  • 31 + 8702341 = 8702372
  • 43 + 8702329 = 8702372
  • 61 + 8702311 = 8702372
  • 193 + 8702179 = 8702372
  • 199 + 8702173 = 8702372
  • 223 + 8702149 = 8702372
  • 241 + 8702131 = 8702372

Showing the first eight; more decompositions exist.
