Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425736, here are decompositions:
- 7 + 2147425729 = 2147425736
- 73 + 2147425663 = 2147425736
- 223 + 2147425513 = 2147425736
- 229 + 2147425507 = 2147425736
- 283 + 2147425453 = 2147425736
- 439 + 2147425297 = 2147425736
- 487 + 2147425249 = 2147425736
- 499 + 2147425237 = 2147425736
Showing the first eight; more decompositions exist.
