Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8756420, here are decompositions:

  • 7 + 8756413 = 8756420
  • 19 + 8756401 = 8756420
  • 97 + 8756323 = 8756420
  • 103 + 8756317 = 8756420
  • 157 + 8756263 = 8756420
  • 181 + 8756239 = 8756420
  • 199 + 8756221 = 8756420
  • 271 + 8756149 = 8756420

Showing the first eight; more decompositions exist.
