Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971220, here are decompositions:
- 11 + 4294971209 = 4294971220
- 227 + 4294970993 = 4294971220
- 311 + 4294970909 = 4294971220
- 359 + 4294970861 = 4294971220
- 401 + 4294970819 = 4294971220
- 653 + 4294970567 = 4294971220
- 677 + 4294970543 = 4294971220
- 1031 + 4294970189 = 4294971220
Showing the first eight; more decompositions exist.
