Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13188, here are decompositions:
- 5 + 13183 = 13188
- 11 + 13177 = 13188
- 17 + 13171 = 13188
- 29 + 13159 = 13188
- 37 + 13151 = 13188
- 41 + 13147 = 13188
- 61 + 13127 = 13188
- 67 + 13121 = 13188
Showing the first eight; more decompositions exist.
