Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029680, here are decompositions:
- 37 + 1029643 = 1029680
- 79 + 1029601 = 1029680
- 97 + 1029583 = 1029680
- 103 + 1029577 = 1029680
- 163 + 1029517 = 1029680
- 181 + 1029499 = 1029680
- 193 + 1029487 = 1029680
- 199 + 1029481 = 1029680
Showing the first eight; more decompositions exist.
