Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974878, here are decompositions:
- 67 + 4294974811 = 4294974878
- 109 + 4294974769 = 4294974878
- 421 + 4294974457 = 4294974878
- 547 + 4294974331 = 4294974878
- 739 + 4294974139 = 4294974878
- 829 + 4294974049 = 4294974878
- 967 + 4294973911 = 4294974878
- 1009 + 4294973869 = 4294974878
Showing the first eight; more decompositions exist.
