Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143638, here are decompositions:
- 29 + 143609 = 143638
- 71 + 143567 = 143638
- 101 + 143537 = 143638
- 137 + 143501 = 143638
- 149 + 143489 = 143638
- 251 + 143387 = 143638
- 281 + 143357 = 143638
- 347 + 143291 = 143638
Showing the first eight; more decompositions exist.
