Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612180, here are decompositions:

13 + 8612167 = 8612180
61 + 8612119 = 8612180
193 + 8611987 = 8612180
211 + 8611969 = 8612180
277 + 8611903 = 8612180
307 + 8611873 = 8612180
331 + 8611849 = 8612180
397 + 8611783 = 8612180

Showing the first eight; more decompositions exist.
