Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425622, here are decompositions:
- 31 + 2147425591 = 2147425622
- 103 + 2147425519 = 2147425622
- 109 + 2147425513 = 2147425622
- 211 + 2147425411 = 2147425622
- 229 + 2147425393 = 2147425622
- 241 + 2147425381 = 2147425622
- 313 + 2147425309 = 2147425622
- 373 + 2147425249 = 2147425622
Showing the first eight; more decompositions exist.
