Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99180, here are decompositions:
- 7 + 99173 = 99180
- 31 + 99149 = 99180
- 41 + 99139 = 99180
- 43 + 99137 = 99180
- 47 + 99133 = 99180
- 61 + 99119 = 99180
- 71 + 99109 = 99180
- 97 + 99083 = 99180
Showing the first eight; more decompositions exist.
