Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118188, here are decompositions:
- 17 + 118171 = 118188
- 19 + 118169 = 118188
- 41 + 118147 = 118188
- 61 + 118127 = 118188
- 107 + 118081 = 118188
- 127 + 118061 = 118188
- 131 + 118057 = 118188
- 137 + 118051 = 118188
Showing the first eight; more decompositions exist.
