Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143582, here are decompositions:
- 13 + 143569 = 143582
- 31 + 143551 = 143582
- 73 + 143509 = 143582
- 79 + 143503 = 143582
- 139 + 143443 = 143582
- 163 + 143419 = 143582
- 181 + 143401 = 143582
- 601 + 142981 = 143582
Showing the first eight; more decompositions exist.
