Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86662, here are decompositions:

  • 83 + 86579 = 86662
  • 89 + 86573 = 86662
  • 101 + 86561 = 86662
  • 131 + 86531 = 86662
  • 239 + 86423 = 86662
  • 263 + 86399 = 86662
  • 281 + 86381 = 86662
  • 293 + 86369 = 86662

Showing the first eight; more decompositions exist.
