Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147474250, here are decompositions:
- 11 + 2147474239 = 2147474250
- 37 + 2147474213 = 2147474250
- 101 + 2147474149 = 2147474250
- 127 + 2147474123 = 2147474250
- 137 + 2147474113 = 2147474250
- 157 + 2147474093 = 2147474250
- 179 + 2147474071 = 2147474250
- 223 + 2147474027 = 2147474250
Showing the first eight; more decompositions exist.
