Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39178, here are decompositions:

  • 17 + 39161 = 39178
  • 59 + 39119 = 39178
  • 71 + 39107 = 39178
  • 89 + 39089 = 39178
  • 131 + 39047 = 39178
  • 137 + 39041 = 39178
  • 257 + 38921 = 39178
  • 311 + 38867 = 39178

Showing the first eight; more decompositions exist.
