Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18670, here are decompositions:

  • 53 + 18617 = 18670
  • 83 + 18587 = 18670
  • 131 + 18539 = 18670
  • 149 + 18521 = 18670
  • 167 + 18503 = 18670
  • 227 + 18443 = 18670
  • 257 + 18413 = 18670
  • 269 + 18401 = 18670

Showing the first eight; more decompositions exist.
