Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51994, here are decompositions:

  • 3 + 51991 = 51994
  • 17 + 51977 = 51994
  • 23 + 51971 = 51994
  • 53 + 51941 = 51994
  • 101 + 51893 = 51994
  • 167 + 51827 = 51994
  • 191 + 51803 = 51994
  • 197 + 51797 = 51994

Showing the first eight; more decompositions exist.
