Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488680, here are decompositions:

11 + 33488669 = 33488680
41 + 33488639 = 33488680
53 + 33488627 = 33488680
131 + 33488549 = 33488680
179 + 33488501 = 33488680
311 + 33488369 = 33488680
347 + 33488333 = 33488680
479 + 33488201 = 33488680

Showing the first eight; more decompositions exist.
