Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31459310, here are decompositions:

  • 19 + 31459291 = 31459310
  • 109 + 31459201 = 31459310
  • 199 + 31459111 = 31459310
  • 241 + 31459069 = 31459310
  • 373 + 31458937 = 31459310
  • 397 + 31458913 = 31459310
  • 409 + 31458901 = 31459310
  • 523 + 31458787 = 31459310

Showing the first eight; more decompositions exist.
