Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61860, here are decompositions:

  • 17 + 61843 = 61860
  • 23 + 61837 = 61860
  • 41 + 61819 = 61860
  • 47 + 61813 = 61860
  • 79 + 61781 = 61860
  • 103 + 61757 = 61860
  • 109 + 61751 = 61860
  • 131 + 61729 = 61860

Showing the first eight; more decompositions exist.
