Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021548, here are decompositions:
- 7 + 1021541 = 1021548
- 61 + 1021487 = 1021548
- 107 + 1021441 = 1021548
- 131 + 1021417 = 1021548
- 167 + 1021381 = 1021548
- 179 + 1021369 = 1021548
- 181 + 1021367 = 1021548
- 251 + 1021297 = 1021548
Showing the first eight; more decompositions exist.
