Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66470, here are decompositions:
- 3 + 66467 = 66470
- 7 + 66463 = 66470
- 13 + 66457 = 66470
- 67 + 66403 = 66470
- 97 + 66373 = 66470
- 109 + 66361 = 66470
- 127 + 66343 = 66470
- 199 + 66271 = 66470
Showing the first eight; more decompositions exist.
