Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2912, here are decompositions:

  • 3 + 2909 = 2912
  • 61 + 2851 = 2912
  • 79 + 2833 = 2912
  • 109 + 2803 = 2912
  • 163 + 2749 = 2912
  • 181 + 2731 = 2912
  • 193 + 2719 = 2912
  • 199 + 2713 = 2912

Showing the first eight; more decompositions exist.
