Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31598396, here are decompositions:

  • 19 + 31598377 = 31598396
  • 43 + 31598353 = 31598396
  • 97 + 31598299 = 31598396
  • 157 + 31598239 = 31598396
  • 367 + 31598029 = 31598396
  • 409 + 31597987 = 31598396
  • 463 + 31597933 = 31598396
  • 523 + 31597873 = 31598396

Showing the first eight; more decompositions exist.
