Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294970878, here are decompositions:
- 17 + 4294970861 = 4294970878
- 59 + 4294970819 = 4294970878
- 311 + 4294970567 = 4294970878
- 347 + 4294970531 = 4294970878
- 461 + 4294970417 = 4294970878
- 617 + 4294970261 = 4294970878
- 647 + 4294970231 = 4294970878
- 797 + 4294970081 = 4294970878
Showing the first eight; more decompositions exist.
