Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425866, here are decompositions:
- 13 + 2147425853 = 2147425866
- 107 + 2147425759 = 2147425866
- 137 + 2147425729 = 2147425866
- 307 + 2147425559 = 2147425866
- 347 + 2147425519 = 2147425866
- 353 + 2147425513 = 2147425866
- 359 + 2147425507 = 2147425866
- 409 + 2147425457 = 2147425866
Showing the first eight; more decompositions exist.
