Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972398, here are decompositions:
- 5 + 4294972393 = 4294972398
- 47 + 4294972351 = 4294972398
- 61 + 4294972337 = 4294972398
- 107 + 4294972291 = 4294972398
- 131 + 4294972267 = 4294972398
- 191 + 4294972207 = 4294972398
- 251 + 4294972147 = 4294972398
- 281 + 4294972117 = 4294972398
Showing the first eight; more decompositions exist.
