Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 29912, here are decompositions:

  • 31 + 29881 = 29912
  • 61 + 29851 = 29912
  • 79 + 29833 = 29912
  • 109 + 29803 = 29912
  • 151 + 29761 = 29912
  • 229 + 29683 = 29912
  • 241 + 29671 = 29912
  • 271 + 29641 = 29912

Showing the first eight; more decompositions exist.
