Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547536, here are decompositions:

  • 5 + 31547531 = 31547536
  • 17 + 31547519 = 31547536
  • 29 + 31547507 = 31547536
  • 47 + 31547489 = 31547536
  • 179 + 31547357 = 31547536
  • 197 + 31547339 = 31547536
  • 233 + 31547303 = 31547536
  • 239 + 31547297 = 31547536

Showing the first eight; more decompositions exist.
