Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999258, here are decompositions:
- 19 + 999239 = 999258
- 37 + 999221 = 999258
- 41 + 999217 = 999258
- 59 + 999199 = 999258
- 89 + 999169 = 999258
- 109 + 999149 = 999258
- 157 + 999101 = 999258
- 167 + 999091 = 999258
Showing the first eight; more decompositions exist.
