Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425530, here are decompositions:
- 11 + 2147425519 = 2147425530
- 17 + 2147425513 = 2147425530
- 23 + 2147425507 = 2147425530
- 73 + 2147425457 = 2147425530
- 83 + 2147425447 = 2147425530
- 137 + 2147425393 = 2147425530
- 149 + 2147425381 = 2147425530
- 181 + 2147425349 = 2147425530
Showing the first eight; more decompositions exist.
