Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8730042, here are decompositions:

29 + 8730013 = 8730042
43 + 8729999 = 8730042
59 + 8729983 = 8730042
103 + 8729939 = 8730042
173 + 8729869 = 8730042
193 + 8729849 = 8730042
241 + 8729801 = 8730042
313 + 8729729 = 8730042

Showing the first eight; more decompositions exist.
