Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478994, here are decompositions:

3 + 478991 = 478994
31 + 478963 = 478994
67 + 478927 = 478994
97 + 478897 = 478994
151 + 478843 = 478994
163 + 478831 = 478994
181 + 478813 = 478994
193 + 478801 = 478994

Showing the first eight; more decompositions exist.
