Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425538, here are decompositions:
- 7 + 2147425531 = 2147425538
- 19 + 2147425519 = 2147425538
- 31 + 2147425507 = 2147425538
- 127 + 2147425411 = 2147425538
- 157 + 2147425381 = 2147425538
- 229 + 2147425309 = 2147425538
- 241 + 2147425297 = 2147425538
- 751 + 2147424787 = 2147425538
Showing the first eight; more decompositions exist.
