Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620074, here are decompositions:

5 + 8620069 = 8620074
11 + 8620063 = 8620074
31 + 8620043 = 8620074
131 + 8619943 = 8620074
137 + 8619937 = 8620074
181 + 8619893 = 8620074
191 + 8619883 = 8620074
257 + 8619817 = 8620074

Showing the first eight; more decompositions exist.
