Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738130, here are decompositions:

7 + 8738123 = 8738130
29 + 8738101 = 8738130
41 + 8738089 = 8738130
43 + 8738087 = 8738130
47 + 8738083 = 8738130
59 + 8738071 = 8738130
83 + 8738047 = 8738130
97 + 8738033 = 8738130

Showing the first eight; more decompositions exist.
