Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387152, here are decompositions:
- 89 + 2147387063 = 2147387152
- 149 + 2147387003 = 2147387152
- 269 + 2147386883 = 2147387152
- 419 + 2147386733 = 2147387152
- 569 + 2147386583 = 2147387152
- 881 + 2147386271 = 2147387152
- 941 + 2147386211 = 2147387152
- 983 + 2147386169 = 2147387152
Showing the first eight; more decompositions exist.
