Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978136, here are decompositions:

23 + 978113 = 978136
59 + 978077 = 978136
83 + 978053 = 978136
239 + 977897 = 978136
317 + 977819 = 978136
389 + 977747 = 978136
443 + 977693 = 978136
569 + 977567 = 978136

Showing the first eight; more decompositions exist.
