Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721202, here are decompositions:

  • 5 + 8721197 = 8721202
  • 11 + 8721191 = 8721202
  • 101 + 8721101 = 8721202
  • 173 + 8721029 = 8721202
  • 233 + 8720969 = 8721202
  • 311 + 8720891 = 8721202
  • 383 + 8720819 = 8721202
  • 419 + 8720783 = 8721202

Showing the first eight; more decompositions exist.
