Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498616, here are decompositions:

  • 67 + 31498549 = 31498616
  • 103 + 31498513 = 31498616
  • 337 + 31498279 = 31498616
  • 547 + 31498069 = 31498616
  • 577 + 31498039 = 31498616
  • 607 + 31498009 = 31498616
  • 613 + 31498003 = 31498616
  • 619 + 31497997 = 31498616

Showing the first eight; more decompositions exist.
