Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612072, here are decompositions:

13 + 8612059 = 8612072
61 + 8612011 = 8612072
103 + 8611969 = 8612072
181 + 8611891 = 8612072
193 + 8611879 = 8612072
199 + 8611873 = 8612072
223 + 8611849 = 8612072
283 + 8611789 = 8612072

Showing the first eight; more decompositions exist.
