Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66204, here are decompositions:
- 13 + 66191 = 66204
- 31 + 66173 = 66204
- 43 + 66161 = 66204
- 67 + 66137 = 66204
- 97 + 66107 = 66204
- 101 + 66103 = 66204
- 137 + 66067 = 66204
- 157 + 66047 = 66204
Showing the first eight; more decompositions exist.
