Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138364, here are decompositions:
- 41 + 138323 = 138364
- 53 + 138311 = 138364
- 113 + 138251 = 138364
- 167 + 138197 = 138364
- 173 + 138191 = 138364
- 251 + 138113 = 138364
- 257 + 138107 = 138364
- 263 + 138101 = 138364
Showing the first eight; more decompositions exist.
