Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639292, here are decompositions:

19 + 8639273 = 8639292
29 + 8639263 = 8639292
31 + 8639261 = 8639292
41 + 8639251 = 8639292
43 + 8639249 = 8639292
73 + 8639219 = 8639292
131 + 8639161 = 8639292
139 + 8639153 = 8639292

Showing the first eight; more decompositions exist.
