Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73216, here are decompositions:
- 83 + 73133 = 73216
- 89 + 73127 = 73216
- 137 + 73079 = 73216
- 173 + 73043 = 73216
- 179 + 73037 = 73216
- 197 + 73019 = 73216
- 239 + 72977 = 73216
- 257 + 72959 = 73216
Showing the first eight; more decompositions exist.
