Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620162, here are decompositions:

3 + 8620159 = 8620162
11 + 8620151 = 8620162
29 + 8620133 = 8620162
41 + 8620121 = 8620162
53 + 8620109 = 8620162
113 + 8620049 = 8620162
269 + 8619893 = 8620162
293 + 8619869 = 8620162

Showing the first eight; more decompositions exist.
