Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452794, here are decompositions:

  • 31 + 31452763 = 31452794
  • 67 + 31452727 = 31452794
  • 73 + 31452721 = 31452794
  • 127 + 31452667 = 31452794
  • 211 + 31452583 = 31452794
  • 223 + 31452571 = 31452794
  • 277 + 31452517 = 31452794
  • 313 + 31452481 = 31452794

Showing the first eight; more decompositions exist.
