Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707572, here are decompositions:

  • 151 + 8707421 = 8707572
  • 179 + 8707393 = 8707572
  • 193 + 8707379 = 8707572
  • 229 + 8707343 = 8707572
  • 239 + 8707333 = 8707572
  • 283 + 8707289 = 8707572
  • 331 + 8707241 = 8707572
  • 353 + 8707219 = 8707572

Showing the first eight; more decompositions exist.
