Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658162, here are decompositions:

53 + 8658109 = 8658162
59 + 8658103 = 8658162
61 + 8658101 = 8658162
103 + 8658059 = 8658162
179 + 8657983 = 8658162
193 + 8657969 = 8658162
229 + 8657933 = 8658162
239 + 8657923 = 8658162

Showing the first eight; more decompositions exist.
