Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524590, here are decompositions:

  • 3 + 31524587 = 31524590
  • 67 + 31524523 = 31524590
  • 73 + 31524517 = 31524590
  • 313 + 31524277 = 31524590
  • 367 + 31524223 = 31524590
  • 397 + 31524193 = 31524590
  • 457 + 31524133 = 31524590
  • 499 + 31524091 = 31524590

Showing the first eight; more decompositions exist.
