Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73172, here are decompositions:
- 31 + 73141 = 73172
- 109 + 73063 = 73172
- 163 + 73009 = 73172
- 199 + 72973 = 73172
- 223 + 72949 = 73172
- 241 + 72931 = 73172
- 271 + 72901 = 73172
- 283 + 72889 = 73172
Showing the first eight; more decompositions exist.
