Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623278, here are decompositions:

47 + 33623231 = 33623278
149 + 33623129 = 33623278
179 + 33623099 = 33623278
317 + 33622961 = 33623278
401 + 33622877 = 33623278
419 + 33622859 = 33623278
431 + 33622847 = 33623278
509 + 33622769 = 33623278

Showing the first eight; more decompositions exist.
