Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978042, here are decompositions:

5 + 978037 = 978042
11 + 978031 = 978042
31 + 978011 = 978042
41 + 978001 = 978042
71 + 977971 = 978042
181 + 977861 = 978042
193 + 977849 = 978042
211 + 977831 = 978042

Showing the first eight; more decompositions exist.
