Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498850, here are decompositions:

  • 3 + 31498847 = 31498850
  • 13 + 31498837 = 31498850
  • 37 + 31498813 = 31498850
  • 109 + 31498741 = 31498850
  • 193 + 31498657 = 31498850
  • 211 + 31498639 = 31498850
  • 337 + 31498513 = 31498850
  • 379 + 31498471 = 31498850

Showing the first eight; more decompositions exist.
