Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748438, here are decompositions:

7 + 8748431 = 8748438
19 + 8748419 = 8748438
71 + 8748367 = 8748438
79 + 8748359 = 8748438
107 + 8748331 = 8748438
109 + 8748329 = 8748438
151 + 8748287 = 8748438
157 + 8748281 = 8748438

Showing the first eight; more decompositions exist.
