Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427704, here are decompositions:
- 3 + 2147427701 = 2147427704
- 61 + 2147427643 = 2147427704
- 277 + 2147427427 = 2147427704
- 307 + 2147427397 = 2147427704
- 547 + 2147427157 = 2147427704
- 613 + 2147427091 = 2147427704
- 661 + 2147427043 = 2147427704
- 733 + 2147426971 = 2147427704
Showing the first eight; more decompositions exist.
