Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974782, here are decompositions:
- 13 + 4294974769 = 4294974782
- 199 + 4294974583 = 4294974782
- 331 + 4294974451 = 4294974782
- 421 + 4294974361 = 4294974782
- 643 + 4294974139 = 4294974782
- 733 + 4294974049 = 4294974782
- 829 + 4294973953 = 4294974782
- 859 + 4294973923 = 4294974782
Showing the first eight; more decompositions exist.
