Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730180, here are decompositions:

23 + 8730157 = 8730180
29 + 8730151 = 8730180
31 + 8730149 = 8730180
89 + 8730091 = 8730180
97 + 8730083 = 8730180
103 + 8730077 = 8730180
113 + 8730067 = 8730180
131 + 8730049 = 8730180

Showing the first eight; more decompositions exist.
