Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499024, here are decompositions:

  • 3 + 31499021 = 31499024
  • 31 + 31498993 = 31499024
  • 61 + 31498963 = 31499024
  • 127 + 31498897 = 31499024
  • 157 + 31498867 = 31499024
  • 211 + 31498813 = 31499024
  • 283 + 31498741 = 31499024
  • 367 + 31498657 = 31499024

Showing the first eight; more decompositions exist.
