Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722248, here are decompositions:

  • 11 + 8722237 = 8722248
  • 37 + 8722211 = 8722248
  • 61 + 8722187 = 8722248
  • 79 + 8722169 = 8722248
  • 131 + 8722117 = 8722248
  • 149 + 8722099 = 8722248
  • 151 + 8722097 = 8722248
  • 167 + 8722081 = 8722248

Showing the first eight; more decompositions exist.
