Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477860, here are decompositions:

  • 43 + 33477817 = 33477860
  • 67 + 33477793 = 33477860
  • 181 + 33477679 = 33477860
  • 211 + 33477649 = 33477860
  • 307 + 33477553 = 33477860
  • 337 + 33477523 = 33477860
  • 379 + 33477481 = 33477860
  • 397 + 33477463 = 33477860

Showing the first eight; more decompositions exist.
