Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147447392, here are decompositions:
- 3 + 2147447389 = 2147447392
- 29 + 2147447363 = 2147447392
- 53 + 2147447339 = 2147447392
- 59 + 2147447333 = 2147447392
- 71 + 2147447321 = 2147447392
- 131 + 2147447261 = 2147447392
- 149 + 2147447243 = 2147447392
- 179 + 2147447213 = 2147447392
Showing the first eight; more decompositions exist.
