Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448944, here are decompositions:

  • 41 + 31448903 = 31448944
  • 47 + 31448897 = 31448944
  • 53 + 31448891 = 31448944
  • 227 + 31448717 = 31448944
  • 251 + 31448693 = 31448944
  • 521 + 31448423 = 31448944
  • 563 + 31448381 = 31448944
  • 641 + 31448303 = 31448944

Showing the first eight; more decompositions exist.
