Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573592, here are decompositions:

  • 31 + 31573561 = 31573592
  • 79 + 31573513 = 31573592
  • 199 + 31573393 = 31573592
  • 229 + 31573363 = 31573592
  • 313 + 31573279 = 31573592
  • 331 + 31573261 = 31573592
  • 439 + 31573153 = 31573592
  • 499 + 31573093 = 31573592

Showing the first eight; more decompositions exist.
