Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61884, here are decompositions:

  • 5 + 61879 = 61884
  • 13 + 61871 = 61884
  • 23 + 61861 = 61884
  • 41 + 61843 = 61884
  • 47 + 61837 = 61884
  • 71 + 61813 = 61884
  • 103 + 61781 = 61884
  • 127 + 61757 = 61884

Showing the first eight; more decompositions exist.
