Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544558, here are decompositions:

  • 7 + 31544551 = 31544558
  • 211 + 31544347 = 31544558
  • 277 + 31544281 = 31544558
  • 337 + 31544221 = 31544558
  • 379 + 31544179 = 31544558
  • 547 + 31544011 = 31544558
  • 571 + 31543987 = 31544558
  • 631 + 31543927 = 31544558

Showing the first eight; more decompositions exist.
