Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33557370, here are decompositions:

  • 13 + 33557357 = 33557370
  • 29 + 33557341 = 33557370
  • 31 + 33557339 = 33557370
  • 43 + 33557327 = 33557370
  • 47 + 33557323 = 33557370
  • 53 + 33557317 = 33557370
  • 113 + 33557257 = 33557370
  • 167 + 33557203 = 33557370

Showing the first eight; more decompositions exist.
