Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481668, here are decompositions:
- 17 + 481651 = 481668
- 29 + 481639 = 481668
- 79 + 481589 = 481668
- 97 + 481571 = 481668
- 137 + 481531 = 481668
- 167 + 481501 = 481668
- 179 + 481489 = 481668
- 199 + 481469 = 481668
Showing the first eight; more decompositions exist.
