Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147942, here are decompositions:

  • 5 + 147937 = 147942
  • 23 + 147919 = 147942
  • 61 + 147881 = 147942
  • 79 + 147863 = 147942
  • 83 + 147859 = 147942
  • 89 + 147853 = 147942
  • 131 + 147811 = 147942
  • 149 + 147793 = 147942

Showing the first eight; more decompositions exist.
