Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33473812, here are decompositions:

  • 131 + 33473681 = 33473812
  • 263 + 33473549 = 33473812
  • 269 + 33473543 = 33473812
  • 389 + 33473423 = 33473812
  • 401 + 33473411 = 33473812
  • 431 + 33473381 = 33473812
  • 461 + 33473351 = 33473812
  • 503 + 33473309 = 33473812

Showing the first eight; more decompositions exist.
