Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748390, here are decompositions:

23 + 8748367 = 8748390
29 + 8748361 = 8748390
31 + 8748359 = 8748390
59 + 8748331 = 8748390
61 + 8748329 = 8748390
67 + 8748323 = 8748390
103 + 8748287 = 8748390
109 + 8748281 = 8748390

Showing the first eight; more decompositions exist.
