Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021792, here are decompositions:
- 131 + 1021661 = 1021792
- 251 + 1021541 = 1021792
- 389 + 1021403 = 1021792
- 419 + 1021373 = 1021792
- 461 + 1021331 = 1021792
- 491 + 1021301 = 1021792
- 503 + 1021289 = 1021792
- 509 + 1021283 = 1021792
Showing the first eight; more decompositions exist.
