Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697890, here are decompositions:

  • 31 + 8697859 = 8697890
  • 67 + 8697823 = 8697890
  • 79 + 8697811 = 8697890
  • 193 + 8697697 = 8697890
  • 199 + 8697691 = 8697890
  • 277 + 8697613 = 8697890
  • 283 + 8697607 = 8697890
  • 379 + 8697511 = 8697890

Showing the first eight; more decompositions exist.
