Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667492, here are decompositions:

61 + 8667431 = 8667492
73 + 8667419 = 8667492
79 + 8667413 = 8667492
89 + 8667403 = 8667492
173 + 8667319 = 8667492
179 + 8667313 = 8667492
191 + 8667301 = 8667492
193 + 8667299 = 8667492

Showing the first eight; more decompositions exist.
