Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 998750, here are decompositions:
- 7 + 998743 = 998750
- 13 + 998737 = 998750
- 61 + 998689 = 998750
- 97 + 998653 = 998750
- 127 + 998623 = 998750
- 199 + 998551 = 998750
- 211 + 998539 = 998750
- 223 + 998527 = 998750
Showing the first eight; more decompositions exist.
