Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425692, here are decompositions:
- 11 + 2147425681 = 2147425692
- 29 + 2147425663 = 2147425692
- 101 + 2147425591 = 2147425692
- 151 + 2147425541 = 2147425692
- 173 + 2147425519 = 2147425692
- 179 + 2147425513 = 2147425692
- 239 + 2147425453 = 2147425692
- 281 + 2147425411 = 2147425692
Showing the first eight; more decompositions exist.
