Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621412, here are decompositions:

  • 73 + 8621339 = 8621412
  • 103 + 8621309 = 8621412
  • 113 + 8621299 = 8621412
  • 131 + 8621281 = 8621412
  • 199 + 8621213 = 8621412
  • 211 + 8621201 = 8621412
  • 223 + 8621189 = 8621412
  • 229 + 8621183 = 8621412

Showing the first eight; more decompositions exist.
