Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 64158, here are decompositions:
- 5 + 64153 = 64158
- 7 + 64151 = 64158
- 67 + 64091 = 64158
- 139 + 64019 = 64158
- 151 + 64007 = 64158
- 181 + 63977 = 64158
- 229 + 63929 = 64158
- 251 + 63907 = 64158
Showing the first eight; more decompositions exist.
