Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422084, here are decompositions:
- 23 + 2147422061 = 2147422084
- 47 + 2147422037 = 2147422084
- 131 + 2147421953 = 2147422084
- 173 + 2147421911 = 2147422084
- 191 + 2147421893 = 2147422084
- 251 + 2147421833 = 2147422084
- 347 + 2147421737 = 2147422084
- 491 + 2147421593 = 2147422084
Showing the first eight; more decompositions exist.
