Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452502, here are decompositions:

  • 5 + 31452497 = 31452502
  • 41 + 31452461 = 31452502
  • 83 + 31452419 = 31452502
  • 101 + 31452401 = 31452502
  • 269 + 31452233 = 31452502
  • 293 + 31452209 = 31452502
  • 461 + 31452041 = 31452502
  • 503 + 31451999 = 31452502

Showing the first eight; more decompositions exist.
