Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446904, here are decompositions:

  • 11 + 31446893 = 31446904
  • 263 + 31446641 = 31446904
  • 311 + 31446593 = 31446904
  • 347 + 31446557 = 31446904
  • 443 + 31446461 = 31446904
  • 563 + 31446341 = 31446904
  • 647 + 31446257 = 31446904
  • 653 + 31446251 = 31446904

Showing the first eight; more decompositions exist.
