Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387104, here are decompositions:
- 41 + 2147387063 = 2147387104
- 101 + 2147387003 = 2147387104
- 251 + 2147386853 = 2147387104
- 347 + 2147386757 = 2147387104
- 503 + 2147386601 = 2147387104
- 521 + 2147386583 = 2147387104
- 641 + 2147386463 = 2147387104
- 827 + 2147386277 = 2147387104
Showing the first eight; more decompositions exist.
