Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294964128, here are decompositions:
- 5 + 4294964123 = 4294964128
- 47 + 4294964081 = 4294964128
- 89 + 4294964039 = 4294964128
- 101 + 4294964027 = 4294964128
- 227 + 4294963901 = 4294964128
- 281 + 4294963847 = 4294964128
- 347 + 4294963781 = 4294964128
- 461 + 4294963667 = 4294964128
Showing the first eight; more decompositions exist.
