Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975742, here are decompositions:
- 3 + 4294975739 = 4294975742
- 181 + 4294975561 = 4294975742
- 199 + 4294975543 = 4294975742
- 271 + 4294975471 = 4294975742
- 331 + 4294975411 = 4294975742
- 349 + 4294975393 = 4294975742
- 373 + 4294975369 = 4294975742
- 619 + 4294975123 = 4294975742
Showing the first eight; more decompositions exist.
