Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972272, here are decompositions:
- 5 + 4294972267 = 4294972272
- 29 + 4294972243 = 4294972272
- 163 + 4294972109 = 4294972272
- 179 + 4294972093 = 4294972272
- 193 + 4294972079 = 4294972272
- 211 + 4294972061 = 4294972272
- 223 + 4294972049 = 4294972272
- 233 + 4294972039 = 4294972272
Showing the first eight; more decompositions exist.
