Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610620, here are decompositions:

  • 3 + 8610617 = 8610620
  • 13 + 8610607 = 8610620
  • 19 + 8610601 = 8610620
  • 37 + 8610583 = 8610620
  • 61 + 8610559 = 8610620
  • 97 + 8610523 = 8610620
  • 157 + 8610463 = 8610620
  • 211 + 8610409 = 8610620

Showing the first eight; more decompositions exist.
