Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33493580, here are decompositions:

7 + 33493573 = 33493580
13 + 33493567 = 33493580
31 + 33493549 = 33493580
67 + 33493513 = 33493580
97 + 33493483 = 33493580
193 + 33493387 = 33493580
271 + 33493309 = 33493580
397 + 33493183 = 33493580

Showing the first eight; more decompositions exist.
