Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478202, here are decompositions:

3 + 478199 = 478202
13 + 478189 = 478202
31 + 478171 = 478202
73 + 478129 = 478202
103 + 478099 = 478202
139 + 478063 = 478202
163 + 478039 = 478202
211 + 477991 = 478202

Showing the first eight; more decompositions exist.
