Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33517520, here are decompositions:

7 + 33517513 = 33517520
109 + 33517411 = 33517520
163 + 33517357 = 33517520
313 + 33517207 = 33517520
331 + 33517189 = 33517520
433 + 33517087 = 33517520
499 + 33517021 = 33517520
571 + 33516949 = 33517520

Showing the first eight; more decompositions exist.
