Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547450, here are decompositions:

  • 37 + 31547413 = 31547450
  • 163 + 31547287 = 31547450
  • 241 + 31547209 = 31547450
  • 307 + 31547143 = 31547450
  • 349 + 31547101 = 31547450
  • 373 + 31547077 = 31547450
  • 463 + 31546987 = 31547450
  • 541 + 31546909 = 31547450

Showing the first eight; more decompositions exist.
