Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978182, here are decompositions:

3 + 978179 = 978182
31 + 978151 = 978182
103 + 978079 = 978182
109 + 978073 = 978182
151 + 978031 = 978182
181 + 978001 = 978182
211 + 977971 = 978182
379 + 977803 = 978182

Showing the first eight; more decompositions exist.
