Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147455318, here are decompositions:
- 5 + 2147455313 = 2147455318
- 17 + 2147455301 = 2147455318
- 89 + 2147455229 = 2147455318
- 149 + 2147455169 = 2147455318
- 167 + 2147455151 = 2147455318
- 227 + 2147455091 = 2147455318
- 257 + 2147455061 = 2147455318
- 467 + 2147454851 = 2147455318
Showing the first eight; more decompositions exist.
