Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021496, here are decompositions:
- 13 + 1021483 = 1021496
- 67 + 1021429 = 1021496
- 79 + 1021417 = 1021496
- 109 + 1021387 = 1021496
- 127 + 1021369 = 1021496
- 163 + 1021333 = 1021496
- 193 + 1021303 = 1021496
- 199 + 1021297 = 1021496
Showing the first eight; more decompositions exist.
