Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8665172, here are decompositions:

73 + 8665099 = 8665172
151 + 8665021 = 8665172
181 + 8664991 = 8665172
193 + 8664979 = 8665172
211 + 8664961 = 8665172
223 + 8664949 = 8665172
433 + 8664739 = 8665172
613 + 8664559 = 8665172

Showing the first eight; more decompositions exist.
