Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547292, here are decompositions:

  • 5 + 31547287 = 31547292
  • 11 + 31547281 = 31547292
  • 31 + 31547261 = 31547292
  • 61 + 31547231 = 31547292
  • 83 + 31547209 = 31547292
  • 89 + 31547203 = 31547292
  • 131 + 31547161 = 31547292
  • 149 + 31547143 = 31547292

Showing the first eight; more decompositions exist.
