Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972942, here are decompositions:
- 11 + 4294972931 = 4294972942
- 83 + 4294972859 = 4294972942
- 149 + 4294972793 = 4294972942
- 191 + 4294972751 = 4294972942
- 383 + 4294972559 = 4294972942
- 461 + 4294972481 = 4294972942
- 509 + 4294972433 = 4294972942
- 521 + 4294972421 = 4294972942
Showing the first eight; more decompositions exist.
