Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672180, here are decompositions:

3 + 8672177 = 8672180
19 + 8672161 = 8672180
79 + 8672101 = 8672180
193 + 8671987 = 8672180
199 + 8671981 = 8672180
541 + 8671639 = 8672180
547 + 8671633 = 8672180
607 + 8671573 = 8672180

Showing the first eight; more decompositions exist.
