Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999152, here are decompositions:
- 3 + 999149 = 999152
- 19 + 999133 = 999152
- 61 + 999091 = 999152
- 103 + 999049 = 999152
- 109 + 999043 = 999152
- 163 + 998989 = 999152
- 211 + 998941 = 999152
- 313 + 998839 = 999152
Showing the first eight; more decompositions exist.
