Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548244, here are decompositions:

  • 197 + 31548047 = 31548244
  • 227 + 31548017 = 31548244
  • 251 + 31547993 = 31548244
  • 263 + 31547981 = 31548244
  • 311 + 31547933 = 31548244
  • 383 + 31547861 = 31548244
  • 461 + 31547783 = 31548244
  • 653 + 31547591 = 31548244

Showing the first eight; more decompositions exist.
