Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619404, here are decompositions:

7 + 8619397 = 8619404
61 + 8619343 = 8619404
163 + 8619241 = 8619404
181 + 8619223 = 8619404
193 + 8619211 = 8619404
307 + 8619097 = 8619404
337 + 8619067 = 8619404
373 + 8619031 = 8619404

Showing the first eight; more decompositions exist.
