Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294978388, here are decompositions:
- 7 + 4294978381 = 4294978388
- 61 + 4294978327 = 4294978388
- 79 + 4294978309 = 4294978388
- 139 + 4294978249 = 4294978388
- 157 + 4294978231 = 4294978388
- 241 + 4294978147 = 4294978388
- 307 + 4294978081 = 4294978388
- 331 + 4294978057 = 4294978388
Showing the first eight; more decompositions exist.
