Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8604972, here are decompositions:

11 + 8604961 = 8604972
29 + 8604943 = 8604972
59 + 8604913 = 8604972
109 + 8604863 = 8604972
149 + 8604823 = 8604972
163 + 8604809 = 8604972
191 + 8604781 = 8604972
193 + 8604779 = 8604972

Showing the first eight; more decompositions exist.
