Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547342, here are decompositions:

  • 3 + 31547339 = 31547342
  • 61 + 31547281 = 31547342
  • 139 + 31547203 = 31547342
  • 181 + 31547161 = 31547342
  • 199 + 31547143 = 31547342
  • 241 + 31547101 = 31547342
  • 373 + 31546969 = 31547342
  • 433 + 31546909 = 31547342

Showing the first eight; more decompositions exist.
