Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 168038, here are decompositions:
- 67 + 167971 = 168038
- 127 + 167911 = 168038
- 139 + 167899 = 168038
- 151 + 167887 = 168038
- 229 + 167809 = 168038
- 397 + 167641 = 168038
- 547 + 167491 = 168038
- 601 + 167437 = 168038
Showing the first eight; more decompositions exist.
