Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187752, here are decompositions:

  • 31 + 187721 = 187752
  • 41 + 187711 = 187752
  • 53 + 187699 = 187752
  • 83 + 187669 = 187752
  • 101 + 187651 = 187752
  • 113 + 187639 = 187752
  • 179 + 187573 = 187752
  • 193 + 187559 = 187752

Showing the first eight; more decompositions exist.
