Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478294, here are decompositions:
- 41 + 2147478253 = 2147478294
- 167 + 2147478127 = 2147478294
- 211 + 2147478083 = 2147478294
- 277 + 2147478017 = 2147478294
- 281 + 2147478013 = 2147478294
- 421 + 2147477873 = 2147478294
- 433 + 2147477861 = 2147478294
- 443 + 2147477851 = 2147478294
Showing the first eight; more decompositions exist.
