Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999958, here are decompositions:
- 5 + 999953 = 999958
- 41 + 999917 = 999958
- 149 + 999809 = 999958
- 347 + 999611 = 999958
- 359 + 999599 = 999958
- 467 + 999491 = 999958
- 521 + 999437 = 999958
- 569 + 999389 = 999958
Showing the first eight; more decompositions exist.
