Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30746, here are decompositions:

  • 19 + 30727 = 30746
  • 43 + 30703 = 30746
  • 97 + 30649 = 30746
  • 103 + 30643 = 30746
  • 109 + 30637 = 30746
  • 193 + 30553 = 30746
  • 229 + 30517 = 30746
  • 277 + 30469 = 30746

Showing the first eight; more decompositions exist.
