Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425880, here are decompositions:
- 151 + 2147425729 = 2147425880
- 199 + 2147425681 = 2147425880
- 349 + 2147425531 = 2147425880
- 367 + 2147425513 = 2147425880
- 373 + 2147425507 = 2147425880
- 433 + 2147425447 = 2147425880
- 487 + 2147425393 = 2147425880
- 499 + 2147425381 = 2147425880
Showing the first eight; more decompositions exist.
