Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021738, here are decompositions:
- 41 + 1021697 = 1021738
- 167 + 1021571 = 1021738
- 197 + 1021541 = 1021738
- 251 + 1021487 = 1021738
- 281 + 1021457 = 1021738
- 449 + 1021289 = 1021738
- 467 + 1021271 = 1021738
- 479 + 1021259 = 1021738
Showing the first eight; more decompositions exist.
