Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613620, here are decompositions:

3 + 8613617 = 8613620
61 + 8613559 = 8613620
73 + 8613547 = 8613620
139 + 8613481 = 8613620
157 + 8613463 = 8613620
163 + 8613457 = 8613620
181 + 8613439 = 8613620
193 + 8613427 = 8613620

Showing the first eight; more decompositions exist.
