Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 997408, here are decompositions:
- 17 + 997391 = 997408
- 29 + 997379 = 997408
- 89 + 997319 = 997408
- 101 + 997307 = 997408
- 149 + 997259 = 997408
- 257 + 997151 = 997408
- 311 + 997097 = 997408
- 317 + 997091 = 997408
Showing the first eight; more decompositions exist.
