Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730072, here are decompositions:

5 + 8730067 = 8730072
23 + 8730049 = 8730072
59 + 8730013 = 8730072
73 + 8729999 = 8730072
89 + 8729983 = 8730072
149 + 8729923 = 8730072
191 + 8729881 = 8730072
223 + 8729849 = 8730072

Showing the first eight; more decompositions exist.
