Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387342, here are decompositions:
- 3 + 2147387339 = 2147387342
- 19 + 2147387323 = 2147387342
- 43 + 2147387299 = 2147387342
- 211 + 2147387131 = 2147387342
- 283 + 2147387059 = 2147387342
- 313 + 2147387029 = 2147387342
- 421 + 2147386921 = 2147387342
- 613 + 2147386729 = 2147387342
Showing the first eight; more decompositions exist.
