Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997832, here are decompositions:
- 19 + 997813 = 997832
- 139 + 997693 = 997832
- 151 + 997681 = 997832
- 181 + 997651 = 997832
- 223 + 997609 = 997832
- 379 + 997453 = 997832
- 463 + 997369 = 997832
- 499 + 997333 = 997832
Showing the first eight; more decompositions exist.
