Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294973218, here are decompositions:
- 17 + 4294973201 = 4294973218
- 71 + 4294973147 = 4294973218
- 101 + 4294973117 = 4294973218
- 149 + 4294973069 = 4294973218
- 359 + 4294972859 = 4294973218
- 467 + 4294972751 = 4294973218
- 491 + 4294972727 = 4294973218
- 659 + 4294972559 = 4294973218
Showing the first eight; more decompositions exist.
