Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662210, here are decompositions:

23 + 8662187 = 8662210
41 + 8662169 = 8662210
59 + 8662151 = 8662210
83 + 8662127 = 8662210
101 + 8662109 = 8662210
131 + 8662079 = 8662210
173 + 8662037 = 8662210
191 + 8662019 = 8662210

Showing the first eight; more decompositions exist.
