Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730160, here are decompositions:

3 + 8730157 = 8730160
11 + 8730149 = 8730160
83 + 8730077 = 8730160
293 + 8729867 = 8730160
311 + 8729849 = 8730160
359 + 8729801 = 8730160
431 + 8729729 = 8730160
443 + 8729717 = 8730160

Showing the first eight; more decompositions exist.
