Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471506, here are decompositions:

  • 37 + 31471469 = 31471506
  • 67 + 31471439 = 31471506
  • 109 + 31471397 = 31471506
  • 149 + 31471357 = 31471506
  • 293 + 31471213 = 31471506
  • 359 + 31471147 = 31471506
  • 383 + 31471123 = 31471506
  • 397 + 31471109 = 31471506

Showing the first eight; more decompositions exist.
