Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294969778, here are decompositions:
- 19 + 4294969759 = 4294969778
- 31 + 4294969747 = 4294969778
- 97 + 4294969681 = 4294969778
- 181 + 4294969597 = 4294969778
- 277 + 4294969501 = 4294969778
- 349 + 4294969429 = 4294969778
- 499 + 4294969279 = 4294969778
- 571 + 4294969207 = 4294969778
Showing the first eight; more decompositions exist.
