Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448588, here are decompositions:

  • 7 + 31448581 = 31448588
  • 37 + 31448551 = 31448588
  • 109 + 31448479 = 31448588
  • 139 + 31448449 = 31448588
  • 211 + 31448377 = 31448588
  • 307 + 31448281 = 31448588
  • 397 + 31448191 = 31448588
  • 439 + 31448149 = 31448588

Showing the first eight; more decompositions exist.
