Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622140, here are decompositions:

3 + 8622137 = 8622140
13 + 8622127 = 8622140
139 + 8622001 = 8622140
151 + 8621989 = 8622140
157 + 8621983 = 8622140
181 + 8621959 = 8622140
193 + 8621947 = 8622140
229 + 8621911 = 8622140

Showing the first eight; more decompositions exist.
