Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978386, here are decompositions:

37 + 978349 = 978386
43 + 978343 = 978386
103 + 978283 = 978386
109 + 978277 = 978386
163 + 978223 = 978386
229 + 978157 = 978386
307 + 978079 = 978386
313 + 978073 = 978386

Showing the first eight; more decompositions exist.
