Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730156, here are decompositions:

5 + 8730151 = 8730156
7 + 8730149 = 8730156
53 + 8730103 = 8730156
73 + 8730083 = 8730156
79 + 8730077 = 8730156
89 + 8730067 = 8730156
107 + 8730049 = 8730156
157 + 8729999 = 8730156

Showing the first eight; more decompositions exist.
