Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138328, here are decompositions:
- 5 + 138323 = 138328
- 17 + 138311 = 138328
- 89 + 138239 = 138328
- 131 + 138197 = 138328
- 137 + 138191 = 138328
- 149 + 138179 = 138328
- 227 + 138101 = 138328
- 251 + 138077 = 138328
Showing the first eight; more decompositions exist.
