Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487660, here are decompositions:

29 + 33487631 = 33487660
53 + 33487607 = 33487660
149 + 33487511 = 33487660
317 + 33487343 = 33487660
347 + 33487313 = 33487660
359 + 33487301 = 33487660
383 + 33487277 = 33487660
389 + 33487271 = 33487660

Showing the first eight; more decompositions exist.
