Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161108, here are decompositions:
- 37 + 161071 = 161108
- 61 + 161047 = 161108
- 127 + 160981 = 161108
- 139 + 160969 = 161108
- 229 + 160879 = 161108
- 397 + 160711 = 161108
- 421 + 160687 = 161108
- 439 + 160669 = 161108
Showing the first eight; more decompositions exist.
