Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546618, here are decompositions:

  • 17 + 31546601 = 31546618
  • 149 + 31546469 = 31546618
  • 167 + 31546451 = 31546618
  • 197 + 31546421 = 31546618
  • 269 + 31546349 = 31546618
  • 281 + 31546337 = 31546618
  • 317 + 31546301 = 31546618
  • 401 + 31546217 = 31546618

Showing the first eight; more decompositions exist.
