Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425844, here are decompositions:
- 163 + 2147425681 = 2147425844
- 181 + 2147425663 = 2147425844
- 313 + 2147425531 = 2147425844
- 331 + 2147425513 = 2147425844
- 337 + 2147425507 = 2147425844
- 397 + 2147425447 = 2147425844
- 433 + 2147425411 = 2147425844
- 463 + 2147425381 = 2147425844
Showing the first eight; more decompositions exist.
