Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978152, here are decompositions:

3 + 978149 = 978152
61 + 978091 = 978152
73 + 978079 = 978152
79 + 978073 = 978152
103 + 978049 = 978152
151 + 978001 = 978152
181 + 977971 = 978152
229 + 977923 = 978152

Showing the first eight; more decompositions exist.
