Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655404, here are decompositions:

3 + 8655401 = 8655404
61 + 8655343 = 8655404
73 + 8655331 = 8655404
97 + 8655307 = 8655404
193 + 8655211 = 8655404
367 + 8655037 = 8655404
397 + 8655007 = 8655404
463 + 8654941 = 8655404

Showing the first eight; more decompositions exist.
