Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147387232, here are decompositions:
- 5 + 2147387227 = 2147387232
- 13 + 2147387219 = 2147387232
- 19 + 2147387213 = 2147387232
- 79 + 2147387153 = 2147387232
- 101 + 2147387131 = 2147387232
- 149 + 2147387083 = 2147387232
- 173 + 2147387059 = 2147387232
- 223 + 2147387009 = 2147387232
Showing the first eight; more decompositions exist.
