Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620086, here are decompositions:

17 + 8620069 = 8620086
23 + 8620063 = 8620086
37 + 8620049 = 8620086
43 + 8620043 = 8620086
89 + 8619997 = 8620086
149 + 8619937 = 8620086
193 + 8619893 = 8620086
227 + 8619859 = 8620086

Showing the first eight; more decompositions exist.
