Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164680, here are decompositions:
- 3 + 164677 = 164680
- 17 + 164663 = 164680
- 53 + 164627 = 164680
- 59 + 164621 = 164680
- 149 + 164531 = 164680
- 167 + 164513 = 164680
- 233 + 164447 = 164680
- 251 + 164429 = 164680
Showing the first eight; more decompositions exist.
