Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79142, here are decompositions:
- 3 + 79139 = 79142
- 31 + 79111 = 79142
- 79 + 79063 = 79142
- 103 + 79039 = 79142
- 163 + 78979 = 79142
- 223 + 78919 = 79142
- 241 + 78901 = 79142
- 421 + 78721 = 79142
Showing the first eight; more decompositions exist.
