Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 47132, here are decompositions:

  • 3 + 47129 = 47132
  • 13 + 47119 = 47132
  • 73 + 47059 = 47132
  • 139 + 46993 = 47132
  • 199 + 46933 = 47132
  • 271 + 46861 = 47132
  • 313 + 46819 = 47132
  • 409 + 46723 = 47132

Showing the first eight; more decompositions exist.
