Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667644, here are decompositions:

3 + 8667641 = 8667644
31 + 8667613 = 8667644
43 + 8667601 = 8667644
241 + 8667403 = 8667644
331 + 8667313 = 8667644
373 + 8667271 = 8667644
523 + 8667121 = 8667644
541 + 8667103 = 8667644

Showing the first eight; more decompositions exist.
