Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19180, here are decompositions:

  • 17 + 19163 = 19180
  • 23 + 19157 = 19180
  • 41 + 19139 = 19180
  • 59 + 19121 = 19180
  • 101 + 19079 = 19180
  • 107 + 19073 = 19180
  • 149 + 19031 = 19180
  • 167 + 19013 = 19180

Showing the first eight; more decompositions exist.
