Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620444, here are decompositions:

83 + 8620361 = 8620444
137 + 8620307 = 8620444
167 + 8620277 = 8620444
227 + 8620217 = 8620444
233 + 8620211 = 8620444
257 + 8620187 = 8620444
293 + 8620151 = 8620444
311 + 8620133 = 8620444

Showing the first eight; more decompositions exist.
