Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708520, here are decompositions:

  • 11 + 8708509 = 8708520
  • 13 + 8708507 = 8708520
  • 19 + 8708501 = 8708520
  • 59 + 8708461 = 8708520
  • 71 + 8708449 = 8708520
  • 97 + 8708423 = 8708520
  • 109 + 8708411 = 8708520
  • 127 + 8708393 = 8708520

Showing the first eight; more decompositions exist.
