Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13168, here are decompositions:
- 5 + 13163 = 13168
- 17 + 13151 = 13168
- 41 + 13127 = 13168
- 47 + 13121 = 13168
- 59 + 13109 = 13168
- 131 + 13037 = 13168
- 167 + 13001 = 13168
- 227 + 12941 = 13168
Showing the first eight; more decompositions exist.
