Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446704, here are decompositions:

  • 97 + 31446607 = 31446704
  • 151 + 31446553 = 31446704
  • 277 + 31446427 = 31446704
  • 337 + 31446367 = 31446704
  • 463 + 31446241 = 31446704
  • 571 + 31446133 = 31446704
  • 607 + 31446097 = 31446704
  • 643 + 31446061 = 31446704

Showing the first eight; more decompositions exist.
