Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138734, here are decompositions:
- 3 + 138731 = 138734
- 7 + 138727 = 138734
- 73 + 138661 = 138734
- 97 + 138637 = 138734
- 157 + 138577 = 138734
- 163 + 138571 = 138734
- 223 + 138511 = 138734
- 241 + 138493 = 138734
Showing the first eight; more decompositions exist.
