Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426830, here are decompositions:
- 83 + 2147426747 = 2147426830
- 137 + 2147426693 = 2147426830
- 149 + 2147426681 = 2147426830
- 173 + 2147426657 = 2147426830
- 179 + 2147426651 = 2147426830
- 257 + 2147426573 = 2147426830
- 359 + 2147426471 = 2147426830
- 431 + 2147426399 = 2147426830
Showing the first eight; more decompositions exist.
