Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33610990, here are decompositions:

  • 3 + 33610987 = 33610990
  • 107 + 33610883 = 33610990
  • 113 + 33610877 = 33610990
  • 131 + 33610859 = 33610990
  • 359 + 33610631 = 33610990
  • 521 + 33610469 = 33610990
  • 593 + 33610397 = 33610990
  • 683 + 33610307 = 33610990

Showing the first eight; more decompositions exist.
