Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999516, here are decompositions:
- 17 + 999499 = 999516
- 79 + 999437 = 999516
- 83 + 999433 = 999516
- 127 + 999389 = 999516
- 139 + 999377 = 999516
- 157 + 999359 = 999516
- 229 + 999287 = 999516
- 277 + 999239 = 999516
Showing the first eight; more decompositions exist.
