Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027640, here are decompositions:
- 43 + 1027597 = 1027640
- 73 + 1027567 = 1027640
- 151 + 1027489 = 1027640
- 157 + 1027483 = 1027640
- 181 + 1027459 = 1027640
- 223 + 1027417 = 1027640
- 283 + 1027357 = 1027640
- 379 + 1027261 = 1027640
Showing the first eight; more decompositions exist.
