Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971478, here are decompositions:
- 47 + 4294971431 = 4294971478
- 89 + 4294971389 = 4294971478
- 101 + 4294971377 = 4294971478
- 251 + 4294971227 = 4294971478
- 257 + 4294971221 = 4294971478
- 269 + 4294971209 = 4294971478
- 401 + 4294971077 = 4294971478
- 419 + 4294971059 = 4294971478
Showing the first eight; more decompositions exist.
