Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957872, here are decompositions:
- 11 + 4294957861 = 4294957872
- 13 + 4294957859 = 4294957872
- 19 + 4294957853 = 4294957872
- 31 + 4294957841 = 4294957872
- 173 + 4294957699 = 4294957872
- 193 + 4294957679 = 4294957872
- 229 + 4294957643 = 4294957872
- 263 + 4294957609 = 4294957872
Showing the first eight; more decompositions exist.
