Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15850, here are decompositions:

  • 41 + 15809 = 15850
  • 47 + 15803 = 15850
  • 53 + 15797 = 15850
  • 59 + 15791 = 15850
  • 83 + 15767 = 15850
  • 89 + 15761 = 15850
  • 101 + 15749 = 15850
  • 113 + 15737 = 15850

Showing the first eight; more decompositions exist.
