Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33619978, here are decompositions:

  • 5 + 33619973 = 33619978
  • 59 + 33619919 = 33619978
  • 131 + 33619847 = 33619978
  • 167 + 33619811 = 33619978
  • 179 + 33619799 = 33619978
  • 239 + 33619739 = 33619978
  • 311 + 33619667 = 33619978
  • 389 + 33619589 = 33619978

Showing the first eight; more decompositions exist.
