Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387032, here are decompositions:
- 3 + 2147387029 = 2147387032
- 23 + 2147387009 = 2147387032
- 29 + 2147387003 = 2147387032
- 149 + 2147386883 = 2147387032
- 179 + 2147386853 = 2147387032
- 431 + 2147386601 = 2147387032
- 449 + 2147386583 = 2147387032
- 503 + 2147386529 = 2147387032
Showing the first eight; more decompositions exist.
