Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615694, here are decompositions:

  • 31 + 31615663 = 31615694
  • 43 + 31615651 = 31615694
  • 151 + 31615543 = 31615694
  • 211 + 31615483 = 31615694
  • 223 + 31615471 = 31615694
  • 277 + 31615417 = 31615694
  • 373 + 31615321 = 31615694
  • 421 + 31615273 = 31615694

Showing the first eight; more decompositions exist.
