Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730138, here are decompositions:

47 + 8730091 = 8730138
61 + 8730077 = 8730138
71 + 8730067 = 8730138
89 + 8730049 = 8730138
139 + 8729999 = 8730138
199 + 8729939 = 8730138
251 + 8729887 = 8730138
257 + 8729881 = 8730138

Showing the first eight; more decompositions exist.
