Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28212, here are decompositions:

  • 11 + 28201 = 28212
  • 29 + 28183 = 28212
  • 31 + 28181 = 28212
  • 61 + 28151 = 28212
  • 89 + 28123 = 28212
  • 101 + 28111 = 28212
  • 103 + 28109 = 28212
  • 113 + 28099 = 28212

Showing the first eight; more decompositions exist.
