Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158174, here are decompositions:
- 13 + 158161 = 158174
- 31 + 158143 = 158174
- 61 + 158113 = 158174
- 97 + 158077 = 158174
- 103 + 158071 = 158174
- 127 + 158047 = 158174
- 157 + 158017 = 158174
- 223 + 157951 = 158174
Showing the first eight; more decompositions exist.
