Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620532, here are decompositions:

3 + 8620529 = 8620532
103 + 8620429 = 8620532
139 + 8620393 = 8620532
163 + 8620369 = 8620532
313 + 8620219 = 8620532
373 + 8620159 = 8620532
421 + 8620111 = 8620532
463 + 8620069 = 8620532

Showing the first eight; more decompositions exist.
