Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973870, here are decompositions:
- 3 + 4294973867 = 4294973870
- 79 + 4294973791 = 4294973870
- 127 + 4294973743 = 4294973870
- 157 + 4294973713 = 4294973870
- 199 + 4294973671 = 4294973870
- 241 + 4294973629 = 4294973870
- 277 + 4294973593 = 4294973870
- 283 + 4294973587 = 4294973870
Showing the first eight; more decompositions exist.
