Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147447394, here are decompositions:
- 5 + 2147447389 = 2147447394
- 11 + 2147447383 = 2147447394
- 31 + 2147447363 = 2147447394
- 47 + 2147447347 = 2147447394
- 61 + 2147447333 = 2147447394
- 73 + 2147447321 = 2147447394
- 151 + 2147447243 = 2147447394
- 163 + 2147447231 = 2147447394
Showing the first eight; more decompositions exist.
