Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547494, here are decompositions:

  • 5 + 31547489 = 31547494
  • 23 + 31547471 = 31547494
  • 53 + 31547441 = 31547494
  • 137 + 31547357 = 31547494
  • 191 + 31547303 = 31547494
  • 197 + 31547297 = 31547494
  • 227 + 31547267 = 31547494
  • 233 + 31547261 = 31547494

Showing the first eight; more decompositions exist.
