Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422252, here are decompositions:
- 11 + 2147422241 = 2147422252
- 23 + 2147422229 = 2147422252
- 113 + 2147422139 = 2147422252
- 191 + 2147422061 = 2147422252
- 233 + 2147422019 = 2147422252
- 263 + 2147421989 = 2147422252
- 359 + 2147421893 = 2147422252
- 419 + 2147421833 = 2147422252
Showing the first eight; more decompositions exist.
