Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33530972, here are decompositions:

3 + 33530969 = 33530972
73 + 33530899 = 33530972
199 + 33530773 = 33530972
271 + 33530701 = 33530972
379 + 33530593 = 33530972
421 + 33530551 = 33530972
523 + 33530449 = 33530972
571 + 33530401 = 33530972

Showing the first eight; more decompositions exist.
