Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975388, here are decompositions:
- 19 + 4294975369 = 4294975388
- 241 + 4294975147 = 4294975388
- 271 + 4294975117 = 4294975388
- 331 + 4294975057 = 4294975388
- 337 + 4294975051 = 4294975388
- 397 + 4294974991 = 4294975388
- 577 + 4294974811 = 4294975388
- 619 + 4294974769 = 4294975388
Showing the first eight; more decompositions exist.
