Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725722, here are decompositions:

  • 23 + 8725699 = 8725722
  • 41 + 8725681 = 8725722
  • 53 + 8725669 = 8725722
  • 79 + 8725643 = 8725722
  • 101 + 8725621 = 8725722
  • 113 + 8725609 = 8725722
  • 151 + 8725571 = 8725722
  • 191 + 8725531 = 8725722

Showing the first eight; more decompositions exist.
