Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99380, here are decompositions:
- 3 + 99377 = 99380
- 13 + 99367 = 99380
- 31 + 99349 = 99380
- 103 + 99277 = 99380
- 139 + 99241 = 99380
- 157 + 99223 = 99380
- 199 + 99181 = 99380
- 241 + 99139 = 99380
Showing the first eight; more decompositions exist.
