Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623778, here are decompositions:

79 + 33623699 = 33623778
127 + 33623651 = 33623778
137 + 33623641 = 33623778
157 + 33623621 = 33623778
179 + 33623599 = 33623778
191 + 33623587 = 33623778
271 + 33623507 = 33623778
281 + 33623497 = 33623778

Showing the first eight; more decompositions exist.
