Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738402, here are decompositions:

3 + 8738399 = 8738402
19 + 8738383 = 8738402
103 + 8738299 = 8738402
109 + 8738293 = 8738402
139 + 8738263 = 8738402
163 + 8738239 = 8738402
193 + 8738209 = 8738402
241 + 8738161 = 8738402

Showing the first eight; more decompositions exist.
