Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989942, here are decompositions:
- 3 + 989939 = 989942
- 13 + 989929 = 989942
- 73 + 989869 = 989942
- 103 + 989839 = 989942
- 139 + 989803 = 989942
- 181 + 989761 = 989942
- 193 + 989749 = 989942
- 199 + 989743 = 989942
Showing the first eight; more decompositions exist.
