Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974742, here are decompositions:
- 5 + 4294974737 = 4294974742
- 11 + 4294974731 = 4294974742
- 89 + 4294974653 = 4294974742
- 101 + 4294974641 = 4294974742
- 173 + 4294974569 = 4294974742
- 263 + 4294974479 = 4294974742
- 419 + 4294974323 = 4294974742
- 503 + 4294974239 = 4294974742
Showing the first eight; more decompositions exist.
