Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66180, here are decompositions:
- 7 + 66173 = 66180
- 11 + 66169 = 66180
- 19 + 66161 = 66180
- 43 + 66137 = 66180
- 71 + 66109 = 66180
- 73 + 66107 = 66180
- 97 + 66083 = 66180
- 109 + 66071 = 66180
Showing the first eight; more decompositions exist.
