Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172318, here are decompositions:
- 5 + 172313 = 172318
- 11 + 172307 = 172318
- 59 + 172259 = 172318
- 101 + 172217 = 172318
- 137 + 172181 = 172318
- 149 + 172169 = 172318
- 191 + 172127 = 172318
- 239 + 172079 = 172318
Showing the first eight; more decompositions exist.
