Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564616, here are decompositions:

  • 3 + 31564613 = 31564616
  • 157 + 31564459 = 31564616
  • 229 + 31564387 = 31564616
  • 283 + 31564333 = 31564616
  • 367 + 31564249 = 31564616
  • 373 + 31564243 = 31564616
  • 379 + 31564237 = 31564616
  • 409 + 31564207 = 31564616

Showing the first eight; more decompositions exist.
