Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294963918, here are decompositions:
- 17 + 4294963901 = 4294963918
- 71 + 4294963847 = 4294963918
- 131 + 4294963787 = 4294963918
- 137 + 4294963781 = 4294963918
- 251 + 4294963667 = 4294963918
- 281 + 4294963637 = 4294963918
- 347 + 4294963571 = 4294963918
- 419 + 4294963499 = 4294963918
Showing the first eight; more decompositions exist.
