Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619282, here are decompositions:

13 + 8619269 = 8619282
19 + 8619263 = 8619282
41 + 8619241 = 8619282
53 + 8619229 = 8619282
59 + 8619223 = 8619282
71 + 8619211 = 8619282
83 + 8619199 = 8619282
131 + 8619151 = 8619282

Showing the first eight; more decompositions exist.
