Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426998, here are decompositions:
- 47 + 2147426951 = 2147426998
- 251 + 2147426747 = 2147426998
- 317 + 2147426681 = 2147426998
- 347 + 2147426651 = 2147426998
- 599 + 2147426399 = 2147426998
- 659 + 2147426339 = 2147426998
- 839 + 2147426159 = 2147426998
- 881 + 2147426117 = 2147426998
Showing the first eight; more decompositions exist.
