Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79172, here are decompositions:
- 13 + 79159 = 79172
- 19 + 79153 = 79172
- 61 + 79111 = 79172
- 109 + 79063 = 79172
- 193 + 78979 = 79172
- 271 + 78901 = 79172
- 283 + 78889 = 79172
- 349 + 78823 = 79172
Showing the first eight; more decompositions exist.
