Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974638, here are decompositions:
- 181 + 4294974457 = 4294974638
- 277 + 4294974361 = 4294974638
- 307 + 4294974331 = 4294974638
- 499 + 4294974139 = 4294974638
- 727 + 4294973911 = 4294974638
- 739 + 4294973899 = 4294974638
- 769 + 4294973869 = 4294974638
- 967 + 4294973671 = 4294974638
Showing the first eight; more decompositions exist.
