Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988178, here are decompositions:
- 31 + 988147 = 988178
- 67 + 988111 = 988178
- 109 + 988069 = 988178
- 127 + 988051 = 988178
- 157 + 988021 = 988178
- 181 + 987997 = 988178
- 199 + 987979 = 988178
- 439 + 987739 = 988178
Showing the first eight; more decompositions exist.
