Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487500, here are decompositions:

  • 23 + 33487477 = 33487500
  • 83 + 33487417 = 33487500
  • 107 + 33487393 = 33487500
  • 113 + 33487387 = 33487500
  • 157 + 33487343 = 33487500
  • 181 + 33487319 = 33487500
  • 191 + 33487309 = 33487500
  • 199 + 33487301 = 33487500

Showing the first eight; more decompositions exist.
