Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523848, here are decompositions:

  • 47 + 31523801 = 31523848
  • 179 + 31523669 = 31523848
  • 197 + 31523651 = 31523848
  • 269 + 31523579 = 31523848
  • 311 + 31523537 = 31523848
  • 449 + 31523399 = 31523848
  • 467 + 31523381 = 31523848
  • 569 + 31523279 = 31523848

Showing the first eight; more decompositions exist.
