Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521994, here are decompositions:
- 13 + 521981 = 521994
- 71 + 521923 = 521994
- 97 + 521897 = 521994
- 107 + 521887 = 521994
- 113 + 521881 = 521994
- 163 + 521831 = 521994
- 181 + 521813 = 521994
- 227 + 521767 = 521994
Showing the first eight; more decompositions exist.
