Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706042, here are decompositions:

29 + 8706013 = 8706042
31 + 8706011 = 8706042
41 + 8706001 = 8706042
43 + 8705999 = 8706042
73 + 8705969 = 8706042
83 + 8705959 = 8706042
101 + 8705941 = 8706042
131 + 8705911 = 8706042

Showing the first eight; more decompositions exist.
