Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619402, here are decompositions:

5 + 8619397 = 8619402
59 + 8619343 = 8619402
139 + 8619263 = 8619402
173 + 8619229 = 8619402
179 + 8619223 = 8619402
191 + 8619211 = 8619402
251 + 8619151 = 8619402
271 + 8619131 = 8619402

Showing the first eight; more decompositions exist.
