Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524888, here are decompositions:

  • 79 + 31524809 = 31524888
  • 97 + 31524791 = 31524888
  • 167 + 31524721 = 31524888
  • 211 + 31524677 = 31524888
  • 281 + 31524607 = 31524888
  • 347 + 31524541 = 31524888
  • 379 + 31524509 = 31524888
  • 389 + 31524499 = 31524888

Showing the first eight; more decompositions exist.
