Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625164, here are decompositions:

  • 17 + 31625147 = 31625164
  • 107 + 31625057 = 31625164
  • 257 + 31624907 = 31625164
  • 383 + 31624781 = 31625164
  • 401 + 31624763 = 31625164
  • 491 + 31624673 = 31625164
  • 503 + 31624661 = 31625164
  • 521 + 31624643 = 31625164

Showing the first eight; more decompositions exist.
