Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19186, here are decompositions:

  • 3 + 19183 = 19186
  • 5 + 19181 = 19186
  • 23 + 19163 = 19186
  • 29 + 19157 = 19186
  • 47 + 19139 = 19186
  • 107 + 19079 = 19186
  • 113 + 19073 = 19186
  • 149 + 19037 = 19186

Showing the first eight; more decompositions exist.
