Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66698, here are decompositions:
- 97 + 66601 = 66698
- 127 + 66571 = 66698
- 157 + 66541 = 66698
- 199 + 66499 = 66698
- 241 + 66457 = 66698
- 337 + 66361 = 66698
- 397 + 66301 = 66698
- 631 + 66067 = 66698
Showing the first eight; more decompositions exist.
