Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751420, here are decompositions:

  • 19 + 8751401 = 8751420
  • 53 + 8751367 = 8751420
  • 71 + 8751349 = 8751420
  • 79 + 8751341 = 8751420
  • 101 + 8751319 = 8751420
  • 131 + 8751289 = 8751420
  • 163 + 8751257 = 8751420
  • 199 + 8751221 = 8751420

Showing the first eight; more decompositions exist.
