Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66464, here are decompositions:
- 7 + 66457 = 66464
- 61 + 66403 = 66464
- 103 + 66361 = 66464
- 127 + 66337 = 66464
- 163 + 66301 = 66464
- 193 + 66271 = 66464
- 397 + 66067 = 66464
- 613 + 65851 = 66464
Showing the first eight; more decompositions exist.
