Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978282, here are decompositions:

5 + 978277 = 978282
13 + 978269 = 978282
43 + 978239 = 978282
59 + 978223 = 978282
73 + 978209 = 978282
79 + 978203 = 978282
101 + 978181 = 978282
103 + 978179 = 978282

Showing the first eight; more decompositions exist.
