Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021268, here are decompositions:
- 7 + 1021261 = 1021268
- 109 + 1021159 = 1021268
- 139 + 1021129 = 1021268
- 181 + 1021087 = 1021268
- 271 + 1020997 = 1021268
- 277 + 1020991 = 1021268
- 307 + 1020961 = 1021268
- 337 + 1020931 = 1021268
Showing the first eight; more decompositions exist.
