Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667432, here are decompositions:

5 + 8667427 = 8667432
13 + 8667419 = 8667432
19 + 8667413 = 8667432
29 + 8667403 = 8667432
61 + 8667371 = 8667432
83 + 8667349 = 8667432
113 + 8667319 = 8667432
131 + 8667301 = 8667432

Showing the first eight; more decompositions exist.
