Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730140, here are decompositions:

37 + 8730103 = 8730140
73 + 8730067 = 8730140
127 + 8730013 = 8730140
157 + 8729983 = 8730140
163 + 8729977 = 8730140
271 + 8729869 = 8730140
373 + 8729767 = 8730140
499 + 8729641 = 8730140

Showing the first eight; more decompositions exist.
