Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602140, here are decompositions:

31 + 8602109 = 8602140
97 + 8602043 = 8602140
101 + 8602039 = 8602140
109 + 8602031 = 8602140
139 + 8602001 = 8602140
149 + 8601991 = 8602140
179 + 8601961 = 8602140
193 + 8601947 = 8602140

Showing the first eight; more decompositions exist.
