Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 499488, here are decompositions:
- 5 + 499483 = 499488
- 7 + 499481 = 499488
- 29 + 499459 = 499488
- 97 + 499391 = 499488
- 127 + 499361 = 499488
- 139 + 499349 = 499488
- 167 + 499321 = 499488
- 179 + 499309 = 499488
Showing the first eight; more decompositions exist.
