Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751740, here are decompositions:

  • 7 + 8751733 = 8751740
  • 13 + 8751727 = 8751740
  • 73 + 8751667 = 8751740
  • 163 + 8751577 = 8751740
  • 271 + 8751469 = 8751740
  • 313 + 8751427 = 8751740
  • 373 + 8751367 = 8751740
  • 421 + 8751319 = 8751740

Showing the first eight; more decompositions exist.
