Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294970728, here are decompositions:
- 5 + 4294970723 = 4294970728
- 197 + 4294970531 = 4294970728
- 311 + 4294970417 = 4294970728
- 467 + 4294970261 = 4294970728
- 641 + 4294970087 = 4294970728
- 647 + 4294970081 = 4294970728
- 821 + 4294969907 = 4294970728
- 827 + 4294969901 = 4294970728
Showing the first eight; more decompositions exist.
