Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426788, here are decompositions:
- 41 + 2147426747 = 2147426788
- 107 + 2147426681 = 2147426788
- 131 + 2147426657 = 2147426788
- 137 + 2147426651 = 2147426788
- 317 + 2147426471 = 2147426788
- 389 + 2147426399 = 2147426788
- 449 + 2147426339 = 2147426788
- 641 + 2147426147 = 2147426788
Showing the first eight; more decompositions exist.
