Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670040, here are decompositions:

  • 3 + 8670037 = 8670040
  • 11 + 8670029 = 8670040
  • 47 + 8669993 = 8670040
  • 59 + 8669981 = 8670040
  • 101 + 8669939 = 8670040
  • 179 + 8669861 = 8670040
  • 263 + 8669777 = 8670040
  • 383 + 8669657 = 8670040

Showing the first eight; more decompositions exist.
