Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427046, here are decompositions:
- 3 + 2147427043 = 2147427046
- 5 + 2147427041 = 2147427046
- 353 + 2147426693 = 2147427046
- 389 + 2147426657 = 2147427046
- 503 + 2147426543 = 2147427046
- 587 + 2147426459 = 2147427046
- 647 + 2147426399 = 2147427046
- 839 + 2147426207 = 2147427046
Showing the first eight; more decompositions exist.
