Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118170, here are decompositions:
- 7 + 118163 = 118170
- 23 + 118147 = 118170
- 43 + 118127 = 118170
- 89 + 118081 = 118170
- 109 + 118061 = 118170
- 113 + 118057 = 118170
- 127 + 118043 = 118170
- 137 + 118033 = 118170
Showing the first eight; more decompositions exist.
