Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73178, here are decompositions:
- 37 + 73141 = 73178
- 139 + 73039 = 73178
- 181 + 72997 = 73178
- 229 + 72949 = 73178
- 241 + 72937 = 73178
- 271 + 72907 = 73178
- 277 + 72901 = 73178
- 307 + 72871 = 73178
Showing the first eight; more decompositions exist.
