Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988190, here are decompositions:
- 43 + 988147 = 988190
- 61 + 988129 = 988190
- 79 + 988111 = 988190
- 97 + 988093 = 988190
- 139 + 988051 = 988190
- 157 + 988033 = 988190
- 193 + 987997 = 988190
- 199 + 987991 = 988190
Showing the first eight; more decompositions exist.
