Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147474228, here are decompositions:
- 79 + 2147474149 = 2147474228
- 157 + 2147474071 = 2147474228
- 199 + 2147474029 = 2147474228
- 307 + 2147473921 = 2147474228
- 331 + 2147473897 = 2147474228
- 337 + 2147473891 = 2147474228
- 379 + 2147473849 = 2147474228
- 661 + 2147473567 = 2147474228
Showing the first eight; more decompositions exist.
