Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294963278, here are decompositions:
- 41 + 4294963237 = 4294963278
- 107 + 4294963171 = 4294963278
- 167 + 4294963111 = 4294963278
- 181 + 4294963097 = 4294963278
- 227 + 4294963051 = 4294963278
- 239 + 4294963039 = 4294963278
- 349 + 4294962929 = 4294963278
- 367 + 4294962911 = 4294963278
Showing the first eight; more decompositions exist.
