Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471184, here are decompositions:

  • 13 + 31471171 = 31471184
  • 37 + 31471147 = 31471184
  • 61 + 31471123 = 31471184
  • 193 + 31470991 = 31471184
  • 271 + 31470913 = 31471184
  • 331 + 31470853 = 31471184
  • 337 + 31470847 = 31471184
  • 397 + 31470787 = 31471184

Showing the first eight; more decompositions exist.
