Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294968640, here are decompositions:
- 3 + 4294968637 = 4294968640
- 107 + 4294968533 = 4294968640
- 227 + 4294968413 = 4294968640
- 239 + 4294968401 = 4294968640
- 251 + 4294968389 = 4294968640
- 269 + 4294968371 = 4294968640
- 293 + 4294968347 = 4294968640
- 311 + 4294968329 = 4294968640
Showing the first eight; more decompositions exist.
