Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525446, here are decompositions:

  • 67 + 31525379 = 31525446
  • 79 + 31525367 = 31525446
  • 103 + 31525343 = 31525446
  • 157 + 31525289 = 31525446
  • 163 + 31525283 = 31525446
  • 167 + 31525279 = 31525446
  • 179 + 31525267 = 31525446
  • 233 + 31525213 = 31525446

Showing the first eight; more decompositions exist.
