Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 21014, here are decompositions:

  • 3 + 21011 = 21014
  • 13 + 21001 = 21014
  • 31 + 20983 = 21014
  • 67 + 20947 = 21014
  • 127 + 20887 = 21014
  • 157 + 20857 = 21014
  • 241 + 20773 = 21014
  • 271 + 20743 = 21014

Showing the first eight; more decompositions exist.
