Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730130, here are decompositions:

47 + 8730083 = 8730130
53 + 8730077 = 8730130
131 + 8729999 = 8730130
191 + 8729939 = 8730130
263 + 8729867 = 8730130
281 + 8729849 = 8730130
293 + 8729837 = 8730130
401 + 8729729 = 8730130

Showing the first eight; more decompositions exist.
