Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757822, here are decompositions:

5 + 8757817 = 8757822
13 + 8757809 = 8757822
23 + 8757799 = 8757822
53 + 8757769 = 8757822
103 + 8757719 = 8757822
109 + 8757713 = 8757822
131 + 8757691 = 8757822
163 + 8757659 = 8757822

Showing the first eight; more decompositions exist.
