Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61866, here are decompositions:

  • 5 + 61861 = 61866
  • 23 + 61843 = 61866
  • 29 + 61837 = 61866
  • 47 + 61819 = 61866
  • 53 + 61813 = 61866
  • 109 + 61757 = 61866
  • 137 + 61729 = 61866
  • 149 + 61717 = 61866

Showing the first eight; more decompositions exist.
