Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147447824, here are decompositions:
- 17 + 2147447807 = 2147447824
- 47 + 2147447777 = 2147447824
- 101 + 2147447723 = 2147447824
- 167 + 2147447657 = 2147447824
- 227 + 2147447597 = 2147447824
- 251 + 2147447573 = 2147447824
- 461 + 2147447363 = 2147447824
- 491 + 2147447333 = 2147447824
Showing the first eight; more decompositions exist.
