Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999492, here are decompositions:
- 41 + 999451 = 999492
- 59 + 999433 = 999492
- 61 + 999431 = 999492
- 103 + 999389 = 999492
- 163 + 999329 = 999492
- 223 + 999269 = 999492
- 271 + 999221 = 999492
- 293 + 999199 = 999492
Showing the first eight; more decompositions exist.
