Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30564, here are decompositions:

  • 5 + 30559 = 30564
  • 7 + 30557 = 30564
  • 11 + 30553 = 30564
  • 47 + 30517 = 30564
  • 67 + 30497 = 30564
  • 71 + 30493 = 30564
  • 73 + 30491 = 30564
  • 97 + 30467 = 30564

Showing the first eight; more decompositions exist.
