Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748090, here are decompositions:

47 + 8748043 = 8748090
59 + 8748031 = 8748090
73 + 8748017 = 8748090
79 + 8748011 = 8748090
89 + 8748001 = 8748090
103 + 8747987 = 8748090
149 + 8747941 = 8748090
157 + 8747933 = 8748090

Showing the first eight; more decompositions exist.
