Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473492, here are decompositions:
- 5 + 2147473487 = 2147473492
- 23 + 2147473469 = 2147473492
- 83 + 2147473409 = 2147473492
- 191 + 2147473301 = 2147473492
- 251 + 2147473241 = 2147473492
- 431 + 2147473061 = 2147473492
- 443 + 2147473049 = 2147473492
- 569 + 2147472923 = 2147473492
Showing the first eight; more decompositions exist.
