Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526156, here are decompositions:

  • 73 + 31526083 = 31526156
  • 199 + 31525957 = 31526156
  • 229 + 31525927 = 31526156
  • 307 + 31525849 = 31526156
  • 373 + 31525783 = 31526156
  • 379 + 31525777 = 31526156
  • 433 + 31525723 = 31526156
  • 439 + 31525717 = 31526156

Showing the first eight; more decompositions exist.
