Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619464, here are decompositions:

  • 5 + 31619459 = 31619464
  • 137 + 31619327 = 31619464
  • 197 + 31619267 = 31619464
  • 251 + 31619213 = 31619464
  • 257 + 31619207 = 31619464
  • 281 + 31619183 = 31619464
  • 293 + 31619171 = 31619464
  • 347 + 31619117 = 31619464

Showing the first eight; more decompositions exist.
