Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623978, here are decompositions:

67 + 33623911 = 33623978
79 + 33623899 = 33623978
127 + 33623851 = 33623978
139 + 33623839 = 33623978
181 + 33623797 = 33623978
277 + 33623701 = 33623978
337 + 33623641 = 33623978
379 + 33623599 = 33623978

Showing the first eight; more decompositions exist.
