Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702520, here are decompositions:

  • 17 + 8702503 = 8702520
  • 23 + 8702497 = 8702520
  • 31 + 8702489 = 8702520
  • 37 + 8702483 = 8702520
  • 61 + 8702459 = 8702520
  • 89 + 8702431 = 8702520
  • 109 + 8702411 = 8702520
  • 149 + 8702371 = 8702520

Showing the first eight; more decompositions exist.
