Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978106, here are decompositions:

29 + 978077 = 978106
53 + 978053 = 978106
89 + 978017 = 978106
179 + 977927 = 978106
257 + 977849 = 978106
293 + 977813 = 978106
359 + 977747 = 978106
383 + 977723 = 978106

Showing the first eight; more decompositions exist.
