Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971928, here are decompositions:
- 431 + 4294971497 = 4294971928
- 659 + 4294971269 = 4294971928
- 701 + 4294971227 = 4294971928
- 719 + 4294971209 = 4294971928
- 827 + 4294971101 = 4294971928
- 1019 + 4294970909 = 4294971928
- 1049 + 4294970879 = 4294971928
- 1109 + 4294970819 = 4294971928
Showing the first eight; more decompositions exist.
