Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473684, here are decompositions:

  • 101 + 31473583 = 31473684
  • 103 + 31473581 = 31473684
  • 197 + 31473487 = 31473684
  • 227 + 31473457 = 31473684
  • 271 + 31473413 = 31473684
  • 353 + 31473331 = 31473684
  • 401 + 31473283 = 31473684
  • 421 + 31473263 = 31473684

Showing the first eight; more decompositions exist.
