Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38840, here are decompositions:

  • 7 + 38833 = 38840
  • 19 + 38821 = 38840
  • 37 + 38803 = 38840
  • 73 + 38767 = 38840
  • 103 + 38737 = 38840
  • 127 + 38713 = 38840
  • 163 + 38677 = 38840
  • 211 + 38629 = 38840

Showing the first eight; more decompositions exist.
