Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387160, here are decompositions:
- 7 + 2147387153 = 2147387160
- 29 + 2147387131 = 2147387160
- 97 + 2147387063 = 2147387160
- 101 + 2147387059 = 2147387160
- 131 + 2147387029 = 2147387160
- 151 + 2147387009 = 2147387160
- 157 + 2147387003 = 2147387160
- 173 + 2147386987 = 2147387160
Showing the first eight; more decompositions exist.
