Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425928, here are decompositions:
- 199 + 2147425729 = 2147425928
- 337 + 2147425591 = 2147425928
- 397 + 2147425531 = 2147425928
- 409 + 2147425519 = 2147425928
- 421 + 2147425507 = 2147425928
- 547 + 2147425381 = 2147425928
- 619 + 2147425309 = 2147425928
- 631 + 2147425297 = 2147425928
Showing the first eight; more decompositions exist.
