Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748210, here are decompositions:

7 + 8748203 = 8748210
11 + 8748199 = 8748210
19 + 8748191 = 8748210
43 + 8748167 = 8748210
67 + 8748143 = 8748210
73 + 8748137 = 8748210
101 + 8748109 = 8748210
113 + 8748097 = 8748210

Showing the first eight; more decompositions exist.
