Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488388, here are decompositions:

7 + 33488381 = 33488388
19 + 33488369 = 33488388
79 + 33488309 = 33488388
107 + 33488281 = 33488388
251 + 33488137 = 33488388
257 + 33488131 = 33488388
281 + 33488107 = 33488388
347 + 33488041 = 33488388

Showing the first eight; more decompositions exist.
