Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487530, here are decompositions:

17 + 33487513 = 33487530
19 + 33487511 = 33487530
23 + 33487507 = 33487530
53 + 33487477 = 33487530
79 + 33487451 = 33487530
107 + 33487423 = 33487530
113 + 33487417 = 33487530
137 + 33487393 = 33487530

Showing the first eight; more decompositions exist.
