Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526020, here are decompositions:

  • 101 + 31525919 = 31526020
  • 107 + 31525913 = 31526020
  • 131 + 31525889 = 31526020
  • 179 + 31525841 = 31526020
  • 233 + 31525787 = 31526020
  • 257 + 31525763 = 31526020
  • 419 + 31525601 = 31526020
  • 431 + 31525589 = 31526020

Showing the first eight; more decompositions exist.
