Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957878, here are decompositions:
- 17 + 4294957861 = 4294957878
- 19 + 4294957859 = 4294957878
- 37 + 4294957841 = 4294957878
- 97 + 4294957781 = 4294957878
- 149 + 4294957729 = 4294957878
- 179 + 4294957699 = 4294957878
- 181 + 4294957697 = 4294957878
- 199 + 4294957679 = 4294957878
Showing the first eight; more decompositions exist.
