Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33526280, here are decompositions:

  • 13 + 33526267 = 33526280
  • 79 + 33526201 = 33526280
  • 97 + 33526183 = 33526280
  • 157 + 33526123 = 33526280
  • 331 + 33525949 = 33526280
  • 349 + 33525931 = 33526280
  • 379 + 33525901 = 33526280
  • 397 + 33525883 = 33526280

Showing the first eight; more decompositions exist.
