Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610142, here are decompositions:

3 + 8610139 = 8610142
5 + 8610137 = 8610142
29 + 8610113 = 8610142
41 + 8610101 = 8610142
179 + 8609963 = 8610142
251 + 8609891 = 8610142
263 + 8609879 = 8610142
293 + 8609849 = 8610142

Showing the first eight; more decompositions exist.
