Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387426, here are decompositions:
- 13 + 2147387413 = 2147387426
- 43 + 2147387383 = 2147387426
- 103 + 2147387323 = 2147387426
- 127 + 2147387299 = 2147387426
- 199 + 2147387227 = 2147387426
- 367 + 2147387059 = 2147387426
- 397 + 2147387029 = 2147387426
- 409 + 2147387017 = 2147387426
Showing the first eight; more decompositions exist.
