Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473934, here are decompositions:
- 13 + 2147473921 = 2147473934
- 37 + 2147473897 = 2147473934
- 43 + 2147473891 = 2147473934
- 97 + 2147473837 = 2147473934
- 367 + 2147473567 = 2147473934
- 457 + 2147473477 = 2147473934
- 643 + 2147473291 = 2147473934
- 1051 + 2147472883 = 2147473934
Showing the first eight; more decompositions exist.
