Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705578, here are decompositions:

  • 5 + 8705573 = 8705578
  • 17 + 8705561 = 8705578
  • 29 + 8705549 = 8705578
  • 47 + 8705531 = 8705578
  • 59 + 8705519 = 8705578
  • 71 + 8705507 = 8705578
  • 137 + 8705441 = 8705578
  • 149 + 8705429 = 8705578

Showing the first eight; more decompositions exist.
