Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524558, here are decompositions:

  • 17 + 31524541 = 31524558
  • 41 + 31524517 = 31524558
  • 59 + 31524499 = 31524558
  • 89 + 31524469 = 31524558
  • 139 + 31524419 = 31524558
  • 227 + 31524331 = 31524558
  • 257 + 31524301 = 31524558
  • 281 + 31524277 = 31524558

Showing the first eight; more decompositions exist.
