Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973728, here are decompositions:
- 11 + 4294973717 = 4294973728
- 179 + 4294973549 = 4294973728
- 191 + 4294973537 = 4294973728
- 197 + 4294973531 = 4294973728
- 251 + 4294973477 = 4294973728
- 659 + 4294973069 = 4294973728
- 797 + 4294972931 = 4294973728
- 977 + 4294972751 = 4294973728
Showing the first eight; more decompositions exist.
