Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658906, here are decompositions:

13 + 8658893 = 8658906
19 + 8658887 = 8658906
29 + 8658877 = 8658906
37 + 8658869 = 8658906
59 + 8658847 = 8658906
149 + 8658757 = 8658906
167 + 8658739 = 8658906
197 + 8658709 = 8658906

Showing the first eight; more decompositions exist.
