Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528520, here are decompositions:

  • 19 + 31528501 = 31528520
  • 61 + 31528459 = 31528520
  • 73 + 31528447 = 31528520
  • 157 + 31528363 = 31528520
  • 193 + 31528327 = 31528520
  • 229 + 31528291 = 31528520
  • 241 + 31528279 = 31528520
  • 307 + 31528213 = 31528520

Showing the first eight; more decompositions exist.
