Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143528, here are decompositions:
- 19 + 143509 = 143528
- 61 + 143467 = 143528
- 67 + 143461 = 143528
- 109 + 143419 = 143528
- 127 + 143401 = 143528
- 199 + 143329 = 143528
- 241 + 143287 = 143528
- 271 + 143257 = 143528
Showing the first eight; more decompositions exist.
