Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66402, here are decompositions:
- 19 + 66383 = 66402
- 29 + 66373 = 66402
- 41 + 66361 = 66402
- 43 + 66359 = 66402
- 59 + 66343 = 66402
- 101 + 66301 = 66402
- 109 + 66293 = 66402
- 131 + 66271 = 66402
Showing the first eight; more decompositions exist.
