Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028370, here are decompositions:
- 37 + 1028333 = 1028370
- 41 + 1028329 = 1028370
- 43 + 1028327 = 1028370
- 53 + 1028317 = 1028370
- 61 + 1028309 = 1028370
- 67 + 1028303 = 1028370
- 97 + 1028273 = 1028370
- 107 + 1028263 = 1028370
Showing the first eight; more decompositions exist.
