Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294970840, here are decompositions:
- 79 + 4294970761 = 4294970840
- 271 + 4294970569 = 4294970840
- 337 + 4294970503 = 4294970840
- 373 + 4294970467 = 4294970840
- 397 + 4294970443 = 4294970840
- 463 + 4294970377 = 4294970840
- 691 + 4294970149 = 4294970840
- 751 + 4294970089 = 4294970840
Showing the first eight; more decompositions exist.
