Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161214, here are decompositions:
- 13 + 161201 = 161214
- 47 + 161167 = 161214
- 73 + 161141 = 161214
- 127 + 161087 = 161214
- 167 + 161047 = 161214
- 181 + 161033 = 161214
- 197 + 161017 = 161214
- 233 + 160981 = 161214
Showing the first eight; more decompositions exist.
