Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528254, here are decompositions:

  • 13 + 31528241 = 31528254
  • 41 + 31528213 = 31528254
  • 47 + 31528207 = 31528254
  • 83 + 31528171 = 31528254
  • 97 + 31528157 = 31528254
  • 103 + 31528151 = 31528254
  • 127 + 31528127 = 31528254
  • 151 + 31528103 = 31528254

Showing the first eight; more decompositions exist.
