Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744864, here are decompositions:

  • 3 + 8744861 = 8744864
  • 31 + 8744833 = 8744864
  • 127 + 8744737 = 8744864
  • 157 + 8744707 = 8744864
  • 181 + 8744683 = 8744864
  • 307 + 8744557 = 8744864
  • 313 + 8744551 = 8744864
  • 367 + 8744497 = 8744864

Showing the first eight; more decompositions exist.
