Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620138, here are decompositions:

5 + 8620133 = 8620138
17 + 8620121 = 8620138
29 + 8620109 = 8620138
89 + 8620049 = 8620138
269 + 8619869 = 8620138
281 + 8619857 = 8620138
347 + 8619791 = 8620138
419 + 8619719 = 8620138

Showing the first eight; more decompositions exist.
