Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73158, here are decompositions:
- 17 + 73141 = 73158
- 31 + 73127 = 73158
- 37 + 73121 = 73158
- 67 + 73091 = 73158
- 79 + 73079 = 73158
- 97 + 73061 = 73158
- 139 + 73019 = 73158
- 149 + 73009 = 73158
Showing the first eight; more decompositions exist.
