Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147425340, here are decompositions:
- 7 + 2147425333 = 2147425340
- 31 + 2147425309 = 2147425340
- 43 + 2147425297 = 2147425340
- 97 + 2147425243 = 2147425340
- 103 + 2147425237 = 2147425340
- 127 + 2147425213 = 2147425340
- 523 + 2147424817 = 2147425340
- 547 + 2147424793 = 2147425340
Showing the first eight; more decompositions exist.
