Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487436, here are decompositions:

13 + 33487423 = 33487436
19 + 33487417 = 33487436
43 + 33487393 = 33487436
127 + 33487309 = 33487436
163 + 33487273 = 33487436
439 + 33486997 = 33487436
607 + 33486829 = 33487436
673 + 33486763 = 33487436

Showing the first eight; more decompositions exist.
