Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001238, here are decompositions:
- 19 + 1001219 = 1001238
- 41 + 1001197 = 1001238
- 47 + 1001191 = 1001238
- 61 + 1001177 = 1001238
- 79 + 1001159 = 1001238
- 131 + 1001107 = 1001238
- 149 + 1001089 = 1001238
- 151 + 1001087 = 1001238
Showing the first eight; more decompositions exist.
