Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957968, here are decompositions:
- 11 + 4294957957 = 4294957968
- 29 + 4294957939 = 4294957968
- 107 + 4294957861 = 4294957968
- 109 + 4294957859 = 4294957968
- 127 + 4294957841 = 4294957968
- 239 + 4294957729 = 4294957968
- 251 + 4294957717 = 4294957968
- 269 + 4294957699 = 4294957968
Showing the first eight; more decompositions exist.
