Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19258, here are decompositions:

  • 47 + 19211 = 19258
  • 101 + 19157 = 19258
  • 137 + 19121 = 19258
  • 179 + 19079 = 19258
  • 227 + 19031 = 19258
  • 257 + 19001 = 19258
  • 311 + 18947 = 19258
  • 347 + 18911 = 19258

Showing the first eight; more decompositions exist.
