Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33574640, here are decompositions:

3 + 33574637 = 33574640
7 + 33574633 = 33574640
19 + 33574621 = 33574640
37 + 33574603 = 33574640
67 + 33574573 = 33574640
79 + 33574561 = 33574640
97 + 33574543 = 33574640
181 + 33574459 = 33574640

Showing the first eight; more decompositions exist.
