Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473980, here are decompositions:
- 17 + 2147473963 = 2147473980
- 59 + 2147473921 = 2147473980
- 83 + 2147473897 = 2147473980
- 89 + 2147473891 = 2147473980
- 131 + 2147473849 = 2147473980
- 193 + 2147473787 = 2147473980
- 199 + 2147473781 = 2147473980
- 277 + 2147473703 = 2147473980
Showing the first eight; more decompositions exist.
