Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5438, here are decompositions:
- 7 + 5431 = 5438
- 19 + 5419 = 5438
- 31 + 5407 = 5438
- 157 + 5281 = 5438
- 211 + 5227 = 5438
- 229 + 5209 = 5438
- 241 + 5197 = 5438
- 271 + 5167 = 5438
Showing the first eight; more decompositions exist.
