Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294959978, here are decompositions:
- 5 + 4294959973 = 4294959978
- 11 + 4294959967 = 4294959978
- 19 + 4294959959 = 4294959978
- 47 + 4294959931 = 4294959978
- 109 + 4294959869 = 4294959978
- 131 + 4294959847 = 4294959978
- 227 + 4294959751 = 4294959978
- 277 + 4294959701 = 4294959978
Showing the first eight; more decompositions exist.
