Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974868, here are decompositions:
- 5 + 4294974863 = 4294974868
- 131 + 4294974737 = 4294974868
- 137 + 4294974731 = 4294974868
- 227 + 4294974641 = 4294974868
- 269 + 4294974599 = 4294974868
- 389 + 4294974479 = 4294974868
- 641 + 4294974227 = 4294974868
- 761 + 4294974107 = 4294974868
Showing the first eight; more decompositions exist.
