Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8603388, here are decompositions:

7 + 8603381 = 8603388
19 + 8603369 = 8603388
41 + 8603347 = 8603388
47 + 8603341 = 8603388
89 + 8603299 = 8603388
137 + 8603251 = 8603388
139 + 8603249 = 8603388
149 + 8603239 = 8603388

Showing the first eight; more decompositions exist.
