Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978312, here are decompositions:

29 + 978283 = 978312
43 + 978269 = 978312
73 + 978239 = 978312
79 + 978233 = 978312
89 + 978223 = 978312
103 + 978209 = 978312
109 + 978203 = 978312
131 + 978181 = 978312

Showing the first eight; more decompositions exist.
