Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967872, here are decompositions:
- 5 + 4294967867 = 4294967872
- 11 + 4294967861 = 4294967872
- 89 + 4294967783 = 4294967872
- 113 + 4294967759 = 4294967872
- 149 + 4294967723 = 4294967872
- 191 + 4294967681 = 4294967872
- 233 + 4294967639 = 4294967872
- 311 + 4294967561 = 4294967872
Showing the first eight; more decompositions exist.
