Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480040, here are decompositions:

  • 19 + 31480021 = 31480040
  • 79 + 31479961 = 31480040
  • 211 + 31479829 = 31480040
  • 223 + 31479817 = 31480040
  • 271 + 31479769 = 31480040
  • 283 + 31479757 = 31480040
  • 421 + 31479619 = 31480040
  • 463 + 31479577 = 31480040

Showing the first eight; more decompositions exist.
