Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988188, here are decompositions:
- 31 + 988157 = 988188
- 41 + 988147 = 988188
- 59 + 988129 = 988188
- 79 + 988109 = 988188
- 127 + 988061 = 988188
- 137 + 988051 = 988188
- 167 + 988021 = 988188
- 181 + 988007 = 988188
Showing the first eight; more decompositions exist.
