Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33625720, here are decompositions:

  • 41 + 33625679 = 33625720
  • 53 + 33625667 = 33625720
  • 59 + 33625661 = 33625720
  • 173 + 33625547 = 33625720
  • 257 + 33625463 = 33625720
  • 269 + 33625451 = 33625720
  • 353 + 33625367 = 33625720
  • 389 + 33625331 = 33625720

Showing the first eight; more decompositions exist.
