Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99218, here are decompositions:
- 37 + 99181 = 99218
- 79 + 99139 = 99218
- 109 + 99109 = 99218
- 139 + 99079 = 99218
- 271 + 98947 = 99218
- 307 + 98911 = 99218
- 331 + 98887 = 99218
- 349 + 98869 = 99218
Showing the first eight; more decompositions exist.
