Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16508, here are decompositions:
- 31 + 16477 = 16508
- 61 + 16447 = 16508
- 97 + 16411 = 16508
- 127 + 16381 = 16508
- 139 + 16369 = 16508
- 241 + 16267 = 16508
- 277 + 16231 = 16508
- 367 + 16141 = 16508
Showing the first eight; more decompositions exist.
