Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158120, here are decompositions:
- 7 + 158113 = 158120
- 43 + 158077 = 158120
- 73 + 158047 = 158120
- 103 + 158017 = 158120
- 223 + 157897 = 158120
- 283 + 157837 = 158120
- 307 + 157813 = 158120
- 349 + 157771 = 158120
Showing the first eight; more decompositions exist.
