Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967280, here are decompositions:
- 83 + 4294967197 = 4294967280
- 137 + 4294967143 = 4294967280
- 193 + 4294967087 = 4294967280
- 251 + 4294967029 = 4294967280
- 283 + 4294966997 = 4294967280
- 337 + 4294966943 = 4294967280
- 353 + 4294966927 = 4294967280
- 467 + 4294966813 = 4294967280
Showing the first eight; more decompositions exist.
