Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39400, here are decompositions:

  • 3 + 39397 = 39400
  • 17 + 39383 = 39400
  • 29 + 39371 = 39400
  • 41 + 39359 = 39400
  • 59 + 39341 = 39400
  • 83 + 39317 = 39400
  • 107 + 39293 = 39400
  • 149 + 39251 = 39400

Showing the first eight; more decompositions exist.
