Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752280, here are decompositions:

  • 7 + 8752273 = 8752280
  • 73 + 8752207 = 8752280
  • 79 + 8752201 = 8752280
  • 127 + 8752153 = 8752280
  • 151 + 8752129 = 8752280
  • 157 + 8752123 = 8752280
  • 223 + 8752057 = 8752280
  • 241 + 8752039 = 8752280

Showing the first eight; more decompositions exist.
