Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33538100, here are decompositions:

19 + 33538081 = 33538100
31 + 33538069 = 33538100
73 + 33538027 = 33538100
97 + 33538003 = 33538100
139 + 33537961 = 33538100
181 + 33537919 = 33538100
331 + 33537769 = 33538100
487 + 33537613 = 33538100

Showing the first eight; more decompositions exist.
