Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971238, here are decompositions:
- 11 + 4294971227 = 4294971238
- 17 + 4294971221 = 4294971238
- 29 + 4294971209 = 4294971238
- 137 + 4294971101 = 4294971238
- 179 + 4294971059 = 4294971238
- 359 + 4294970879 = 4294971238
- 419 + 4294970819 = 4294971238
- 821 + 4294970417 = 4294971238
Showing the first eight; more decompositions exist.
