Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758238, here are decompositions:

19 + 8758219 = 8758238
37 + 8758201 = 8758238
67 + 8758171 = 8758238
109 + 8758129 = 8758238
157 + 8758081 = 8758238
277 + 8757961 = 8758238
409 + 8757829 = 8758238
421 + 8757817 = 8758238

Showing the first eight; more decompositions exist.
