Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425600, here are decompositions:
- 41 + 2147425559 = 2147425600
- 59 + 2147425541 = 2147425600
- 251 + 2147425349 = 2147425600
- 317 + 2147425283 = 2147425600
- 431 + 2147425169 = 2147425600
- 461 + 2147425139 = 2147425600
- 479 + 2147425121 = 2147425600
- 599 + 2147425001 = 2147425600
Showing the first eight; more decompositions exist.
