Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521180, here are decompositions:

3 + 33521177 = 33521180
97 + 33521083 = 33521180
193 + 33520987 = 33521180
241 + 33520939 = 33521180
337 + 33520843 = 33521180
367 + 33520813 = 33521180
379 + 33520801 = 33521180
397 + 33520783 = 33521180

Showing the first eight; more decompositions exist.
