Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978238, here are decompositions:

5 + 978233 = 978238
29 + 978209 = 978238
59 + 978179 = 978238
89 + 978149 = 978238
167 + 978071 = 978238
197 + 978041 = 978238
227 + 978011 = 978238
311 + 977927 = 978238

Showing the first eight; more decompositions exist.
