Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978112, here are decompositions:

41 + 978071 = 978112
59 + 978053 = 978112
71 + 978041 = 978112
101 + 978011 = 978112
251 + 977861 = 978112
263 + 977849 = 978112
281 + 977831 = 978112
293 + 977819 = 978112

Showing the first eight; more decompositions exist.
