Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 38684, here are decompositions:

  • 7 + 38677 = 38684
  • 13 + 38671 = 38684
  • 31 + 38653 = 38684
  • 73 + 38611 = 38684
  • 127 + 38557 = 38684
  • 223 + 38461 = 38684
  • 307 + 38377 = 38684
  • 313 + 38371 = 38684

Showing the first eight; more decompositions exist.
