Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487720, here are decompositions:

  • 3 + 33487717 = 33487720
  • 89 + 33487631 = 33487720
  • 113 + 33487607 = 33487720
  • 269 + 33487451 = 33487720
  • 401 + 33487319 = 33487720
  • 419 + 33487301 = 33487720
  • 443 + 33487277 = 33487720
  • 449 + 33487271 = 33487720

Showing the first eight; more decompositions exist.
