Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618222, here are decompositions:

73 + 8618149 = 8618222
103 + 8618119 = 8618222
139 + 8618083 = 8618222
163 + 8618059 = 8618222
181 + 8618041 = 8618222
229 + 8617993 = 8618222
523 + 8617699 = 8618222
541 + 8617681 = 8618222

Showing the first eight; more decompositions exist.
