Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026380, here are decompositions:
- 67 + 1026313 = 1026380
- 127 + 1026253 = 1026380
- 151 + 1026229 = 1026380
- 163 + 1026217 = 1026380
- 181 + 1026199 = 1026380
- 241 + 1026139 = 1026380
- 307 + 1026073 = 1026380
- 337 + 1026043 = 1026380
Showing the first eight; more decompositions exist.
