Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610072, here are decompositions:

5 + 8610067 = 8610072
11 + 8610061 = 8610072
71 + 8610001 = 8610072
73 + 8609999 = 8610072
109 + 8609963 = 8610072
173 + 8609899 = 8610072
181 + 8609891 = 8610072
193 + 8609879 = 8610072

Showing the first eight; more decompositions exist.
