Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020378, here are decompositions:
- 17 + 1020361 = 1020378
- 41 + 1020337 = 1020378
- 109 + 1020269 = 1020378
- 131 + 1020247 = 1020378
- 241 + 1020137 = 1020378
- 269 + 1020109 = 1020378
- 277 + 1020101 = 1020378
- 367 + 1020011 = 1020378
Showing the first eight; more decompositions exist.
