Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72184, here are decompositions:
- 11 + 72173 = 72184
- 17 + 72167 = 72184
- 23 + 72161 = 72184
- 83 + 72101 = 72184
- 107 + 72077 = 72184
- 131 + 72053 = 72184
- 137 + 72047 = 72184
- 191 + 71993 = 72184
Showing the first eight; more decompositions exist.
