Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972388, here are decompositions:
- 37 + 4294972351 = 4294972388
- 97 + 4294972291 = 4294972388
- 151 + 4294972237 = 4294972388
- 181 + 4294972207 = 4294972388
- 241 + 4294972147 = 4294972388
- 271 + 4294972117 = 4294972388
- 337 + 4294972051 = 4294972388
- 349 + 4294972039 = 4294972388
Showing the first eight; more decompositions exist.
