Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748240, here are decompositions:

31 + 8748209 = 8748240
37 + 8748203 = 8748240
41 + 8748199 = 8748240
73 + 8748167 = 8748240
79 + 8748161 = 8748240
97 + 8748143 = 8748240
103 + 8748137 = 8748240
131 + 8748109 = 8748240

Showing the first eight; more decompositions exist.
