Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30862, here are decompositions:

  • 3 + 30859 = 30862
  • 11 + 30851 = 30862
  • 23 + 30839 = 30862
  • 53 + 30809 = 30862
  • 59 + 30803 = 30862
  • 89 + 30773 = 30862
  • 149 + 30713 = 30862
  • 173 + 30689 = 30862

Showing the first eight; more decompositions exist.
