Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524378, here are decompositions:

  • 47 + 31524331 = 31524378
  • 101 + 31524277 = 31524378
  • 107 + 31524271 = 31524378
  • 181 + 31524197 = 31524378
  • 211 + 31524167 = 31524378
  • 271 + 31524107 = 31524378
  • 331 + 31524047 = 31524378
  • 367 + 31524011 = 31524378

Showing the first eight; more decompositions exist.
