Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621602, here are decompositions:

149 + 8621453 = 8621602
173 + 8621429 = 8621602
191 + 8621411 = 8621602
263 + 8621339 = 8621602
293 + 8621309 = 8621602
359 + 8621243 = 8621602
389 + 8621213 = 8621602
401 + 8621201 = 8621602

Showing the first eight; more decompositions exist.
