Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147447822, here are decompositions:
- 31 + 2147447791 = 2147447822
- 181 + 2147447641 = 2147447822
- 349 + 2147447473 = 2147447822
- 433 + 2147447389 = 2147447822
- 439 + 2147447383 = 2147447822
- 463 + 2147447359 = 2147447822
- 571 + 2147447251 = 2147447822
- 643 + 2147447179 = 2147447822
Showing the first eight; more decompositions exist.
