Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610156, here are decompositions:

17 + 8610139 = 8610156
19 + 8610137 = 8610156
43 + 8610113 = 8610156
89 + 8610067 = 8610156
157 + 8609999 = 8610156
193 + 8609963 = 8610156
229 + 8609927 = 8610156
239 + 8609917 = 8610156

Showing the first eight; more decompositions exist.
