Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452104, here are decompositions:

  • 7 + 31452097 = 31452104
  • 43 + 31452061 = 31452104
  • 97 + 31452007 = 31452104
  • 223 + 31451881 = 31452104
  • 373 + 31451731 = 31452104
  • 487 + 31451617 = 31452104
  • 577 + 31451527 = 31452104
  • 601 + 31451503 = 31452104

Showing the first eight; more decompositions exist.
