Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707212, here are decompositions:

  • 5 + 8707207 = 8707212
  • 23 + 8707189 = 8707212
  • 29 + 8707183 = 8707212
  • 53 + 8707159 = 8707212
  • 89 + 8707123 = 8707212
  • 109 + 8707103 = 8707212
  • 181 + 8707031 = 8707212
  • 191 + 8707021 = 8707212

Showing the first eight; more decompositions exist.
