Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147447848, here are decompositions:
- 41 + 2147447807 = 2147447848
- 71 + 2147447777 = 2147447848
- 101 + 2147447747 = 2147447848
- 179 + 2147447669 = 2147447848
- 191 + 2147447657 = 2147447848
- 239 + 2147447609 = 2147447848
- 251 + 2147447597 = 2147447848
- 389 + 2147447459 = 2147447848
Showing the first eight; more decompositions exist.
