Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603442, here are decompositions:

13 + 8603429 = 8603442
53 + 8603389 = 8603442
61 + 8603381 = 8603442
73 + 8603369 = 8603442
101 + 8603341 = 8603442
149 + 8603293 = 8603442
179 + 8603263 = 8603442
191 + 8603251 = 8603442

Showing the first eight; more decompositions exist.
