Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638092, here are decompositions:

31 + 8638061 = 8638092
41 + 8638051 = 8638092
53 + 8638039 = 8638092
59 + 8638033 = 8638092
101 + 8637991 = 8638092
139 + 8637953 = 8638092
149 + 8637943 = 8638092
163 + 8637929 = 8638092

Showing the first eight; more decompositions exist.
