Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72134, here are decompositions:
- 31 + 72103 = 72134
- 43 + 72091 = 72134
- 61 + 72073 = 72134
- 103 + 72031 = 72134
- 151 + 71983 = 72134
- 163 + 71971 = 72134
- 193 + 71941 = 72134
- 313 + 71821 = 72134
Showing the first eight; more decompositions exist.
