Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425946, here are decompositions:
- 13 + 2147425933 = 2147425946
- 67 + 2147425879 = 2147425946
- 283 + 2147425663 = 2147425946
- 433 + 2147425513 = 2147425946
- 439 + 2147425507 = 2147425946
- 499 + 2147425447 = 2147425946
- 613 + 2147425333 = 2147425946
- 709 + 2147425237 = 2147425946
Showing the first eight; more decompositions exist.
