Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688148, here are decompositions:

  • 5 + 8688143 = 8688148
  • 47 + 8688101 = 8688148
  • 71 + 8688077 = 8688148
  • 89 + 8688059 = 8688148
  • 137 + 8688011 = 8688148
  • 167 + 8687981 = 8688148
  • 257 + 8687891 = 8688148
  • 269 + 8687879 = 8688148

Showing the first eight; more decompositions exist.
