Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487620, here are decompositions:

13 + 33487607 = 33487620
29 + 33487591 = 33487620
41 + 33487579 = 33487620
59 + 33487561 = 33487620
83 + 33487537 = 33487620
107 + 33487513 = 33487620
109 + 33487511 = 33487620
113 + 33487507 = 33487620

Showing the first eight; more decompositions exist.
