Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145318, here are decompositions:
- 11 + 145307 = 145318
- 29 + 145289 = 145318
- 59 + 145259 = 145318
- 179 + 145139 = 145318
- 197 + 145121 = 145318
- 227 + 145091 = 145318
- 281 + 145037 = 145318
- 311 + 145007 = 145318
Showing the first eight; more decompositions exist.
