Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697878, here are decompositions:

  • 19 + 8697859 = 8697878
  • 67 + 8697811 = 8697878
  • 109 + 8697769 = 8697878
  • 181 + 8697697 = 8697878
  • 271 + 8697607 = 8697878
  • 367 + 8697511 = 8697878
  • 379 + 8697499 = 8697878
  • 499 + 8697379 = 8697878

Showing the first eight; more decompositions exist.
