Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473994, here are decompositions:
- 31 + 2147473963 = 2147473994
- 73 + 2147473921 = 2147473994
- 97 + 2147473897 = 2147473994
- 103 + 2147473891 = 2147473994
- 157 + 2147473837 = 2147473994
- 643 + 2147473351 = 2147473994
- 727 + 2147473267 = 2147473994
- 877 + 2147473117 = 2147473994
Showing the first eight; more decompositions exist.
