Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15844, here are decompositions:

  • 41 + 15803 = 15844
  • 47 + 15797 = 15844
  • 53 + 15791 = 15844
  • 71 + 15773 = 15844
  • 83 + 15761 = 15844
  • 107 + 15737 = 15844
  • 113 + 15731 = 15844
  • 173 + 15671 = 15844

Showing the first eight; more decompositions exist.
