Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387694, here are decompositions:
- 17 + 2147387677 = 2147387694
- 43 + 2147387651 = 2147387694
- 47 + 2147387647 = 2147387694
- 163 + 2147387531 = 2147387694
- 191 + 2147387503 = 2147387694
- 281 + 2147387413 = 2147387694
- 311 + 2147387383 = 2147387694
- 467 + 2147387227 = 2147387694
Showing the first eight; more decompositions exist.
