Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294963128, here are decompositions:
- 11 + 4294963117 = 4294963128
- 17 + 4294963111 = 4294963128
- 31 + 4294963097 = 4294963128
- 89 + 4294963039 = 4294963128
- 199 + 4294962929 = 4294963128
- 229 + 4294962899 = 4294963128
- 241 + 4294962887 = 4294963128
- 311 + 4294962817 = 4294963128
Showing the first eight; more decompositions exist.
