Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422082, here are decompositions:
- 19 + 2147422063 = 2147422082
- 199 + 2147421883 = 2147422082
- 229 + 2147421853 = 2147422082
- 313 + 2147421769 = 2147422082
- 373 + 2147421709 = 2147422082
- 409 + 2147421673 = 2147422082
- 433 + 2147421649 = 2147422082
- 541 + 2147421541 = 2147422082
Showing the first eight; more decompositions exist.
