Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426698, here are decompositions:
- 5 + 2147426693 = 2147426698
- 17 + 2147426681 = 2147426698
- 29 + 2147426669 = 2147426698
- 41 + 2147426657 = 2147426698
- 47 + 2147426651 = 2147426698
- 227 + 2147426471 = 2147426698
- 239 + 2147426459 = 2147426698
- 359 + 2147426339 = 2147426698
Showing the first eight; more decompositions exist.
