Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 497648, here are decompositions:
- 61 + 497587 = 497648
- 97 + 497551 = 497648
- 127 + 497521 = 497648
- 139 + 497509 = 497648
- 157 + 497491 = 497648
- 199 + 497449 = 497648
- 367 + 497281 = 497648
- 379 + 497269 = 497648
Showing the first eight; more decompositions exist.
