Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538500, here are decompositions:

  • 19 + 33538481 = 33538500
  • 31 + 33538469 = 33538500
  • 43 + 33538457 = 33538500
  • 53 + 33538447 = 33538500
  • 59 + 33538441 = 33538500
  • 97 + 33538403 = 33538500
  • 113 + 33538387 = 33538500
  • 157 + 33538343 = 33538500

Showing the first eight; more decompositions exist.
