Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4538, here are decompositions:
- 19 + 4519 = 4538
- 31 + 4507 = 4538
- 97 + 4441 = 4538
- 181 + 4357 = 4538
- 199 + 4339 = 4538
- 211 + 4327 = 4538
- 241 + 4297 = 4538
- 277 + 4261 = 4538
Showing the first eight; more decompositions exist.
