Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547716, here are decompositions:

  • 23 + 31547693 = 31547716
  • 107 + 31547609 = 31547716
  • 197 + 31547519 = 31547716
  • 227 + 31547489 = 31547716
  • 257 + 31547459 = 31547716
  • 359 + 31547357 = 31547716
  • 419 + 31547297 = 31547716
  • 449 + 31547267 = 31547716

Showing the first eight; more decompositions exist.
