Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556240, here are decompositions:

  • 83 + 33556157 = 33556240
  • 251 + 33555989 = 33556240
  • 269 + 33555971 = 33556240
  • 281 + 33555959 = 33556240
  • 293 + 33555947 = 33556240
  • 503 + 33555737 = 33556240
  • 593 + 33555647 = 33556240
  • 677 + 33555563 = 33556240

Showing the first eight; more decompositions exist.
